Smooth muscle
The function of the Smooth muscle are the muscle we do not consciously control eg those that are found in the walls of blood and lymphatic vessels, in respiratory, digestive and genito-urinary systems. These muscles work automatically weather we want them to or not.
The structure of the smooth muscle is they have spindle shaped cells with no distant cell membrane and only one nucleus, bundles of the fibre we see with the naked eye.
Skeletal muscle the function is these are the muscle which we consciously control eg or arms, legs. If we want to walk we do so. The structure is the skeletal musclehas cells which make up fibres, each fibre has several nuceli (multi-nucleated cells) and is surrounded by a sheat (sarcolemma). The

The composition of the long bone itself mainly of collagen fibers and an inorganic bone mineral in form of small crystals, In vivo bone (living bone in the bone the body) contains 10% and 20% of water of its dry mass, approximately 60-70% is bone mineral.
Structure of the long bone are those that they are longer than they are wide. They are one of five types of bones, long short flat irregular and seasmoid. Long bones especially the femur and tibia are subjected to most of the load during daily activities and they are crucial for skeletal mobility. The long bone is that it allows movement , particularly in the limbs eg the femur (thigh bone) tibia and fibula (lower leg bones) humerus (upper arm bone), the radius and the ulna (lower arm). Metacarpals (hand bones) metersals (foot bone) and phalanges (finger and toe bone)
Functions of the skeleton
The skeleton is the framework of the body; it supports the softer tissue and provides point of attachment for most skeletal muscles. The skeleton provides mechanical protection for many of the body’s internal organs, redusing risk of injury to them. Skeletal bones are attached to the muscle contract they cause bone to move, packed with over 200 bones, skeletons protect, shape support and move our bodies as well as producing red blood cells in the bone

The coronal structure connects parietal bones. The labroid suture unites the parietal with the occipital.
Ball and socket joint as one in which the rounded surface of a bone fits into and moves within a cup-shaped depression, examples of this type of synovial joint are hip and shoulder joints. The ball-and-socket joint allows freedom of movement up, down, right left and in full 360-degree rotation.
Gliding joints allows two or more flat or slightly rounded bones to move easily together without friction or grinding. The function of a gliding joint is to allow motions such as smooth sliding of bone past bone, bending, stretching and circular motion. Examples of gliding joints include the forearm to wrist arm and lower leg to ankle joint.
Pivot joint is a synovial joint designed with one end fitting like a cylinder like a ring. Pivot joints at the base of the skull and allows the head to rotate. Other pivot points allow the rotation of the
P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue.
Your Inner Fish essay In Neil Shubin’s Your Inner Fish, he takes his readers on a journey throughout time, teaching how marine animals inevitably ended up on land. Shubin starts his book by describing how himself and other paleontologists found a missing piece, that showed how animals transitioned from water to land. With this discovery it allowed paleontologists like Shubin, to see transitions that could possibly link certain species of fish to humans. A major change between fish and humans is the use of limbs and its ability to use its limbs to take itself out of the water and away from the dangers within.
This study examined the differences in articular surface morphology of caudal vertebrae between prehensile and non-prehensile tailed primates. Articular surface is skeletal surface, which includes bone and cartilage, that makes contact with other skeletal surface as part of a joint. Variation in the morphology of articular surface can confer a greater capacity for mechanical loading, which is required for prehensile primates as they often use their tails to suspend their entire weight during locomotion. In this experiment, it was hypothesized that articular surface area and curvature in caudal vertebrae could be used to distinguish between prehensile and non-prehensile tails. The results showed that articular surfaces found in both proximal and distal regions were greater in prehensile tailed primates, in comparison to primates that were non-prehensile tailed.
Chapter six welcomes us into the skeletal system by presenting functions,types,structure, and development of bones. We are also presented the ideas of fractures and even the spine- curling snap of a broken bone which means a band aid simply won 't do! For example, Hematoma formation , Fibrocartilaginous callus, Bony callus ,and Remolding must occur to heal ,aka 3-10 weeks in a signature infested cast ,and if the break eventuated* on your arm, a complementary farmer 's tan. The Axial Skeleton makes an appearance by explaining itself as lying in the middle of the body and consisting of the skull, hyoid bone, vertebral column, thoracic cage, and middle ear bones. The complexity, physiology and delicate fashions of each member of this group is expressed.
• Hip bone • Sternum • Skull • Ribs • Vertebrae • Scapula • The ends of long bones Red marrow is so valuable because it is where blood stem cells are found. Bone broth rich in red marrow provides those stem cell factors which ultimately build your body’s strength and support your immune function A dash of apple cider. ; Bone is an excellent source of calcium and phosphorus, and to a lesser degree, magnesium, sodium, potassium, sulfate and fluoride In the digestion process, hydrochloric acid helps to break down food in the stomach but is also necessary to extract elemental minerals from food.
Memories are an important component to Ng’s novel “Bone.” I think it’s important to note that “Bone” could be called a memory book, because of how it moves in reverse chronological order and through flashbacks. Memories make up the book, but they also play a role within the novel. Memories are a fragment of an important past event. Through memories, we keep the feelings and people in those memories alive, which is what Leila says in the quote above.
Structure Of The Foot: The structure of the foot comprises 26 mostly small bones and 33 joints which form two arches. These bones are held together by the fact that they fit into each other; and fibrous ligaments, muscles and a tough tissue (known as the plantar fascia) support them to retain the shape of the foot. There are also fat pads in the foot, which assist in absorbing impact and with weight bearing. The two major functions of the feet are that act as levers which push the leg forward to enable us to walk; and they help in maintaining body balance by being able to adjust to uneven surfaces.
Many people wonder what should be done with Fortune’s bones, you could keep them on display or burrie them. In my personal opinion, I think that they should be displayed for many reasons. There is a ton of different knowledge behind them and there is a lot of different theories as well. There is so many different people that had the bones. There is added history since the bones have been to so many places and have been touched by so many people.
Collagen, like rope, aims to maximize bones elasticity. And cartilage acts as a buffer. Together these molecules cooperate in order to give bones structure, strength, and support. This relates to animals in the sense that all “animals have molecules that lie between their cells, specifically collagens and proteoglycans.” Through the molecules, cells are able to communicate amongst each other thereby knowing when and how to change their behavior.
Bone cancer isn’t a very common cancer. It accounts for much less than one percent of all cancers. Around 2,300 cases of bone cancer are diagnosed each year. Bone cancer is a serious disease that has multiple different types and treatments.
The Axial Skeleton is the central core of the human body and it protects all the vital organs. It consist of 80 bones in total, 29 bones in the head, 25 bones of the thorax and 26 bones in the vertebral column [8]. The best example for the support and protection function axial skeleton is your skull. There are eight bones in your skull called cranial bone they are thick and hard and lack the ability to move on their own. Their purpose is to protect your brain and its nerves and blood
Almost half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached.
*The pelvic girdle is a duplex structure like pectoral girdle which is made up of three cartilage bones in each half which are known as ossa innominata. *Each os innominatum is formed by three bones *These cartilage bones are – ilium, ischium and pubic. *Dermal bones are lacking in pelvic girdle.
Temporomandibular Joint is a hinge that connects the upper jaw (bone of the skull) and lower jaw (mandible of the jaw) to one another, it is also responsible for the movement of the jaw side to side, forward, and backwards. The temporomandibular joint is comprised of the outside parts of the mandibular fossae of the temporal bone, other ligaments, and parts of the eminences and mandible. This joint is one of the most complex joints in the human body. You can see a lot of the movement of the joint if you open your mouth wide enough. Temporomandibular Joint is usually a result of issues that occur within the jaw, or surrounding muscles in the jaw.
There are millions of these cells inside the human body, and each has a different type of responsibility, or function. There are an infinite amount of cell types, and a few examples of these types are: 1) muscle cells, 2) nerve
