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 aspects that will be explained are movement, protection and the differences. The muscle and skeletal system work together to produce movement. An example of movement is the bones and muscles in the arm that help lift up an object. Tendons are fibrous tissue that connects adjacent bones to a muscle. A tendon is located at the top joint of a bone.
And they locate between the metatarsal. These muscles abduct digit two to four and flex the metatarsophalangeal joints. Only lateral plantar nerve is innervated within these muscles. Skin Skin is the outer part of our body. It covers our body and protects from the outer environment.
The hip joint is the attachment between the hind limb and the axial skeleton. The pelvis girdle consists of two identical hipbones that ventrally meet at the pelvic symphysis. Dorsally they articulate with the sacrum. Each hipbone consists of the ilium, pubis and ischium that have different ossification centers. In adults, these bones are completely fused and their bodies form the cavity for the articulation with the femur, the acetabulum (8).
The capsule of the elbow joint and the annular ligament stabilize the bones proximally. Distally, the bones are connected by a wrist capsule, radio-ulnar stabilizing ligaments (dorsal and volar) and a fibrocartilage articular disk (triangular fibrocartilage compex, TFCC) (). There is an interosseus membrane
The menisci improve congruency between the femoral and condyles of tibia during this movement.27 Figure 8: Articular surfaces of knee joint (A- In extension, B- In flexion). EXTRACAPSULAR LIGAMENTS The ligamentum patellae is attached to the lower border of the patella superiorly and to the tibia tuberosity inferiorly. It is continuation of the central portion of the quadriceps femoris tendon.28 The cordlike lateral collateral ligament is attached superiorly to the lateral condyle of the femur and inferiorly to the head of the fibula. The tendon of the popliteus muscle is present between the lateral collateral ligament and the lateral meniscus.28 The medial collateral ligament is a flat band attached superiorly to the medial femoral condyle and inferiorly to the tibia shaft. It is also attached to the border of the medial meniscus.28 The oblique popliteal ligament is a tendon arising from the semimembranosus muscle.
More osteoclasts can form than osteoblasts, in this case osteoporosis can manifest itself. Bone is also made up of a lot of collagen which is the most abundant protein in the body. There is cancellous bone (spongy, internal bone) and compact bone (harder and external bone). At the joints between bones there is hyaline cartilage that acts as a shock absorber and allows the bones to glide along each other. Inside bones there is a substance called bone marrow.
Muscle is a long bundle of flesh which is attached to the bones at both ends by tendons. Epimysium known as tough tissue which protect outer layer of muscle. Inside the epimysium are fascicles or bundles of muscle fiber cells. The fascicles are surround by a layer of perimysium tissue which act as connective tissue. The individual muscle fiber is covered with endomysium
Anatomically, the patella is of a disproportionate oval-shaped sesamoid bone which articulates with the femoral sulcus. Its proximal attachment is the quadriceps tendon which envelopes the structure and distally at the apex, the patellar tendon attaches. Both the tendons are functional as to stabilise the patella bone in the knee joint during movements or even when the joint is static. Also, the patellar retinacula are attached to both the medial and lateral sides of the patella. When the tendon is overused chronically without given adequate time to heal, tendinosis known as Jumper’s Knee can occur in response to the damage.
The Musculoskeletal System The Musculoskeletal system is made up of muscle, bones, tendons, cartilage, ligaments, nerves and other connective tissues. The main purpose is to support and stabilise the body. The bones work together with the muscles to allow controlled movement and to keep the body’s shape. The bones of the body provide five main functions they are to produce blood cells (white and red), protect body organs (brain, lungs), provided leverage and movement (so we can sit up), and store lipids and minerals (calcium) and to provide structural support for the body: (A support framework for soft tissue and organs). The main function of the Muscular system is movement.
Nonetheless, our group observed specific locations in the skull that over time, changed among species. The following methodology will include how to observe or examine the different locations that were relevant to the study. By looking for the widest part in the back of the skull the location of the maximum skull breath can be identified. The degree of postorbital constriction can be recognized by observing the space behind the brow/supraorbital ridge. The zygomatic flare can be examined by evaluating how wide is the zygomatic bone.
The Appendicular skeleton consists of: PECTORAL GIRDLE (consists of two shoulder blades and two collar bones, which articulate together to allow some movement). UPPER LIMBS (consists of upper arm, forearm, wrist, palm, and fingers that all work together for movement and function of your arm). PELVIC GIRDLE (two large hip bones that provide support for the attachment
The major component of the ligament, muscle, tendon, bone and joint cartilage involved in clubfoot is collagen. Prolidase enzyme activity is required for collagen biosynthesis. Collagen is key for the support of connective tissue. This study called attention to the part of serum prolidase action and its relationship with oxidative-antioxidant status in patients with clubfoot. Collection of blood samples, oxidative stress index, and statistical analysis along with the measurements of serum prolidase activity, total free sulfhydryl groups, total antioxidant capacity and
The objective of the virtual lab on bones consisted of identifying the major bones of the human body. We had to place the major bones of the body in the correct anatomical position. The key terms included the axial skeleton which includes the skull and the bones that support it, such as, the vertebral column, ribs, and sternum. The appendicular skeleton includes the bones of the limbs and the structures that support them such as, the scapula and pelvic bones. It is also noted that where two bones meet is called a joint.
