5 Musculoskeletal System
Function Muscular System – movement, posture, joint stability, and heat production Skeletal System – provide a framework for the body, protect the soft body parts (i.e. brain), store calcium, and produce blood cells They work together  protect, support, and move the body

6 Musculoskeletal System
Bone Structure periosteum outermost layer of the bone, made up of fibrous tissue compact bone dense, hard layers of bone tissue that lie underneath the periostem cancellous (spongy) bone contains little spaces like a sponge and is encased in the layers of compact bone endosteum membranous lining of the hollow cavity of the bone

7 Musculoskeletal System
diaphysis shaft of the long bones epiphysis end of each long bone bone marrow material found in the cavities of bones red marrow: thick, bloodlike material found in flat bones and the ends of long bones; location of blood cell formation yellow marrow: soft, fatty material found in the medullary cavity of long bones

8 Musculoskeletal System
Bone Structure

9 Musculoskeletal System
Skeletal Bones maxilla upper jawbone mandible lower jawbone vertebral column made up of bones called vertebrae (pl.) or vertebra (sing.) through which the spinal cord runs. protects the spinal cord, supports the head, and provides points of attachment for ribs and muscles

10 Musculoskeletal System
cervical vertebrae (C1-C7) first set of 7 bones, forming the neck thoracic vertebrae (T1-T12) second set of 12 vertebrae. They articulate with the 12 pairs of ribs to form the outward curve of the spine lumbar vertebrae (L1-L5) third set of five large vertebrae, which forms the inward curve of the spine sacrum next five vertebrae, which fuse together to form a triangular bone positioned between the two hip bones coccyx four vertebrae fused together to form the tailbone lamina (pl. laminae) part of the vertebral arch

11 Musculoskeletal System
clavicle collarbone scapula should blade acromion process: extension of the scapula, which forms the high point of the shoulder sternum breastbone xiphoid process: lower potion of the sternum humerus upper arm bones

12 Musculoskeletal System
ulna and radius lower arm bones olecranon process projection at the upper end of the ulna that forms the bony point of the elbow carpal bones wrist bones metacarpal bones hand bones phalanges (sing. phalanx) finger and toe bones

13 Musculoskeletal System
pelvic bone, hip bone made up of three bones fused together ischium: lower, rear portion of which one sits ilium: upper, wing-shaped part of each side pubis: anterior portion of the pelvic bone acetabulum large socket in the pelvic bone for the head of the femur femur upper leg bone tibia and fibula lower leg bones

14 Musculoskeletal System
patella(pl. patellae) kneecap tarsal bones ankle bones calcaneus heel bone metatarsal foot bones

15 Bones of the Body

16 Musculoskeletal System
Joints (articulations) Hold bones together articular cartilage smooth layer of firm, fibrous tissue covering the contacting surface of joints meniscus crescent-shaped cartilage found in the knee intervertebral disk cartilaginous pad found between the vertebrae in the spine pubic symphysis cartilaginous joint at which two pubic bones come together

17 Musculoskeletal System
synovia fluid secreted by the synovial membrane and found in joint cavities bursa (pl. bursae) fluid-filled sac that allows for easy movement of one part of a joint over another ligament flexible, tough band of fibrous connective tissue that attaches one bone to another at a joint tendon band of fibrous connective tissue that attches muscle to bone aponeurosis strong sheet of tissue that acts as a tendon to attach muscles to bones

18 Body Joints

19 Musculoskeletal System
Muscles skeletal muscles (striated muscles) attached to bones by tendons and make body movement possible. Skeletal muscles produce action by pulling and by working in pairs. Voluntary muscles because we have control over them smooth muscles (unstriated muscles) located in internal organs such as the walls of blood vessels and the digestive tract. Involuntary muscles b/c they respond to impulses from the autonomic nerves and are not controlled voluntary

20 Musculoskeletal System
cardiac muscle (myocardium) forms most of the wall of the heart. Its involuntary contraction produces the heartbeat

21 Muscles of the Body

22 Types of Muscle

23 Types of Body Movement Term Definition abduction adduction inversion
