Structural and Functional Organization of the Musculoskeletal System Flashcards
Functions of the skeletal system
,Support, Protection, Movement, Mineral homeostasis, Blood cell production, triglyceride storage
What are the different types of bones
Long bones, short bones (almost cubed shaped) Flat bones, irregular bones
What are the parts of a long bone
Diaphysis, Epiphyses, Metaphyses
What are bone building cells?
Osteoblasts
What cells exchange nutrients, maintain bone, and are osteoblasts encased in matrix they build?
Osteocytes
What cells digest bone matrix for normal bone turnover?
Osteoclasts
Joints are dependent on what is between them for classification, such as_____?
presence or absence of space
type of connective that is present between the bones
What are the classifications of joints?
Fibrous, Cartilaginous, Synovial
This type of joint has no cavity, just dense irregular connective tissue
Fibrous
This type of joint has no cavity, bones are held together by cartilage
Cartilaginous joints
What are examples of fibrous joings?
Sutures (located between bones of the skull)
Interosseous membrane (such as tissue between radius-ulna, tib-fib)
What are the structures of synovial joints?
The synovial cavity. (space containing fluid)
articular cartilage (for bone friction reduction)
ligaments
Synovial membrane
Ligaments
menisci
Bursae
What connects bone to bone
ligaments
What connects muscle to bone and is how skeletal muscle contracts and moves bones
tendons
The function of ______ is to cover the end of bones, absorb shock, and reduce friction.
cartilage
