Musculoskeletal assessment Flashcards
What does the musculoskeletal system contain
bones, muscles, and joints
What is the musculoskeletal system controlled by
the nervous system
What is the purpose of the musculoskeletal system
to provide structure and movement for body parts
What is the purpose of bones
structure, protection, serve as levers, store calcium/phosphorus, produce RBCs
What is vitamin C needed for
calcium absorption
How many bones are in the body
206
What are the types of bones
long, short, flat, irregular
What does spongy bone do
help absorb impact
osteoclasts
breakdown and clean up bone
osteoblasts
build bone
Why does bone need blood supply
because it is a living tissue
Joint
a place where two or more bones meet
What is the purpose of a joint
provide a range of motion
Synarthrotic joints
connects two bones with fibrous connective tissue, immovable
Amphiarthrotic joints
joining together of bone through cartilage, partially moveable
Diarthroses/synovial joints
bones attach together through ligaments, have a space between bone filled with synovial fluid, freely moveable
Ball and socket joint
a rounded head (ball) fits into a cup-like structure (socket) to allow movement in all planes in addition to rotation - hip, shoulders
Condyloid joint
an oval shaped bone fits into an elliptical cavity to allow movement in two planes at right angles to each other - wrist
Gliding joint
two flat plane surfaces move past each other - intervertebral joints
Hinge joint
a convex surface fits into a cavity, allowing flexion and extension - knee and elbow
Pivot joint
the joint is formed by a ring-like object that turns on a pivot - first vertebrae and the base of the skull
