The muscular system keeps bones in place and plays a role in the movement of the body. In addition to bones and muscles, the musculoskeletal system also has joints, which has tendons and ligaments within and allows the body to move, and cartilage, which prevents the bone ends from rubbing directly on each other. All of these components together make up the musculoskeletal system.
The musculo skeletal is made of bones, muscles, ligaments and tendons. The purpose of the musculo skeletal system is to protect , support and the overall function of the internal structures and organs of the body. Allow movement, give shape to the body, producing blood cells, storing calcium and phosphorus and producing heat. The skeletal system is made of bones and joints. The skeletal system provides the basic supporting structure of the body.
The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions; support, movement, protection, blood cell production, calcium storage and endocrine regulation that enable us to survive. Below are more details on the exact role the skeletal system has on; protection, shape, support, movement and blood production:
Bone will continue to grow and thicken. Finally, remodeling is the final phase of fracture repair. During the final phase osteoclasts remove excess bony material from both exterior and interior surfaces. Compact bone is now replaced by primary bone. 8.
It has been proven that women generally have wider-set hips than men do. This can cause the knees to turn slightly more inward in women. When running, or jumping, a misalignment of the knees puts excess stress on the ACL, making it more susceptible to an injury. Also, there is a notch located at the distal end of the femur, between the two femoral condyles. This notch in women tends to be slightly smaller and narrower than men, which may decrease or limit the movement of the ACL during the performance of a twisting motion.
This accordance is one of the most important features of skeletal muscles. Muscle mass is the primary indicator of muscle strength and it is not stable. There is continuous process that includes the balance between protein synthesis and catabolism, which determines hypertrophy or atrophy (Blaauw et al., 2013). Increase in muscle proteins during muscle hypertrophy occurs because of either increasing RNA and protein synthesis by existing nuclei or preserving of the same level RNA and protein synthesis from each nuclei and new myonuclei addition to fibers. Because mature muscle fiber myonuclei cannot divide, source of new myonuclei added to fiber is the external of the fiber.
At the base of the trochlear notch and at either side of it are the medial and lateral coronoid process that both the lateral and medial condyles of the humerus rest on the support the dogs weight. The upper end of the radius lies between the coronoid process of the ulna also supporting the dogs
Pressure epiphysis is the ‘’secondary centre of ossification that forms at the articular end of a long bone”. Pressure is involved in the formation of joints. The pressure epiphysis assists transmitting the weight of the body. For example, the head of the femur as a component of the hip joint complex, also the head of the humerus, this forms a part of the shoulder complex.
The rearfoot consists of four bones the distal side of the tibia and fibula (leg bones), the calcaneus (heel bone), and the talus. The plantar fascia originates from the medial calcaneal ligaments, dividing into a medial, central and lateral band that attaches to the superior surface of the abductor hallucis, flexor digitorum brevis, and abductor digiti minimi musculature, respectively. The medial longitudinal arch (MLA) of the foot aids in distributing the force attributed to the weight bearing. The MLA of the foot resembles two rods a rear rod consisting of the calcaneus, talus and an anterior rod consisting of the navicular, three cuneiforms, and the first three metatarsals. These rods are connected at their base by the plantar fascia.
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 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.
