What is an insertion?
An attachment to a movable bone
What is a tendon?
Connects muscle to bone
Define Synarthroses, amphiarthroses, and diarthroses.
Synarthroses: Immovable joints
Amphiarthroses: slightly movable joints
Diarthroses: freely movable joints

What are Synchondroses and give an example?
What are the different ranges of motion of a joint?
Nonaxial, uniaxial, biaxial, multiaxial
An elongated bursa that wraps around the tendon to protect it from friction
What occurs in a gliding movement?
One flat bone surface glides or slips over another similar surface
Abduction vs. adduction
Abduction is away from the midline while adduction is toward the midline
Pronation vs. Supination
Pronation is when the radius rotates over the ulna
Supination is when the radius and ulna are parallel
Dorsiflexion vs. Plantar flexion
Dorsiflexion is pointing your toe to the sky
Plantar is pointing your toes in front of you
Inversion vs. Eversion
inversion: the sole of the foot turned medially
eversion: the sole of the foot faces laterally
