The structure and functions of the musculoskeletal system
bones
The bones in the body

Types of bones
flat
short
long
iregular
function of the skeleton
support
protection of vital organs (by flat bones)
movement
structual shape and points of attachment
mineral storage
blood cell production
muscles

antagonistic pairs
Antagonistic Muscle is a muscle that opposes the action of another. For example, when the triceps oppose the contraction of the flexing biceps by relaxing, the triceps would be regarded as the antagonistic muscle to the biceps whereas the biceps, the agonist muscle
synovial joint
structure of a synovial joint

joints
types of joints
ball and socket (hip,shoulder)
Allow movement in all directions and also rotation.
hinge joints (knee,elbow,ankle)
only allow forwards and backwards movement.
movement at joints
flexion
when the angle of the joint decreases
extenstion
when the angle of the joint increases
adduction
movement towards the midline of the body
abduction
movement away from the midline of the body
rotation
the turning or rotating movement around a single axis
circumduction
the conical (circular) movement of a limb extending from the joint
planter flextion
movement at the ankle joint that points the foot downwards away from the shin
dorsiflexion
movement at the ankle joint that points the foot upwards away from the shin
ligaments and tendons
tendon
a fibrous connective tissue that attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure
ligament
a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable
