Q

Articular Cartilage

A

-shiny, whitish connective tissue
-protects underlying bone
-designed to absorb shock (joint forces), allow movement (smooth surface), and o last (very tough) (it can still be damaged/wear away over time)
-no nerves, no blood vessels

Q

Joint capsule

A

-surrounds and lines the joint
-does not cover the articular cartilage
-makes synovial fluid contained within the joint (synovial fluid has the consistency of egg-white, is clear coloured and 5x more slippery than ice)
-friction between the 2 joint surfaces is minimized by lubrication from the synovial fluid and by the articular cartilage
i.e. cartilage connects the ribs to the breastbone
i.e. the vertebrae are connected by fibrocartilaginous intervertebral disks (pubic symphisis)

Q

Aponeurosis

A

Sheet like tendon

38
Q

Concentric Contraction

A

-when a muscle develops tension, it pulls on the attachments of the muscle
-when the tension is greater than the resistance, the muscle undergoes a shortening or concentric contraction
- a concentric contraction pulls the two attachments closer together

39
Q

Isometric Contraction

A

-when a muscle contracts against a resistance and there is no visible change in the muscle length (it’s attachments are NOT drawn together or pulled apart), it is called an isometric contraction (isometric: equal measure)

40
Q

Eccentric Contraction

A

-when a muscle is generation force but is unable to overcome the force, the muscle will undergo a lengthening or eccentric contraction
-this type of contraction is effectively used to control movements or to act as a brake to movement
-in this type of action, the two muscle attachments are moving away from each other

41
Q

Origin

A

Attachment that is fixed

42
Q

Insertion

A

Attachment that is moving

43
Q

Is it possible for fixed moving attachments to change?

A

Yes

44
Q

Proximal attachment is assumed to be the ____________ and a contraction is assumed to be __________ unless otherwise stated

A

fixed attachment, concentric

45
Q

Prime Mover (a.k.a. the agonist)

A

-primary muscle causing the desired movement (i.e. quad is the prime mover of knee extension)
-there can be more than one prime mover (i.e. hamstrings for flexion of the knee)

46
Q

Antagonist

A

-the muscle that opposes a specific action (i.e. hamstrings perform knee flexion and therefore the antagonists to the quad which perform knee extension)

47
Q

Stabilizers (a.k.a. fixators)

A

-the muscles that stabilize the more proximal joints during actions of the more distal joints (i.e. low back muscles stabilize the trunk so that hip flexors can lift the leg)

48
Q

Synergists (a.k.a. neutralizers, neutralizing synergists)

A

-muscle(s) that work to assist the prime mover in a given action (i.e. there are big calf muscles that point the toes - there are small ones that have this ability too and contribute in a weaker way)
