Q

Single. Fusiform. No striations

A

Smooth muscle

19
Q

Fibrous tissue that attaches muscles to bones

A

Tendons

20
Q

Tendon lies along one side of the muscle and the muscles pass obliquely to it. Give example.

A

Unipennate muscles Ex. EXTENSOR DIGITORUM

21
Q

Bipennate muscles

A

Rectus femoris

Description: tendon lies in the center of the muscle and the muscle fiber pass to it from two sides

22
Q

Multipennate muscles

A

Acromial fibers of the deltoid, tibialis anterior

Des: series of bipennate muscles lying alongside one another or tendon lying on the center …

23
Q

Undesired actions at the proximal joints are prevented by these muscles

A

Synergists

24
Q

Stabilize the proximal joints of a limb, desired movement may occur at a fixed base

A

Fixator

25
Q

Smooth muscle found in

A

BV walls, GIT, GUT

26
Q

Fibrous joints

A

Sutures of vault

Inferior tibiofibular joint

27
Q

Joint in which the bones are united by a plate or bar of hyaline cartilage

A

Primary cartilaginous joint (eg. Union of epiphysis and diaphysis of a growing bone, 1st rib and the manubrium sterni)

NO MOVEMENT POSSIBLE

28
Q

Bones are united by a plate of fibrocartilage and the articular surfaces are covered by a thin layer of hyaline cartilage

A

Secondary cartilaginous joint (eg. Joints between the symphysis pubis and vertebral bodies)

29
Q

Example of plane joints

A

Sternoclavicular, acromioclavicular

30
Q

Pivot joint example

A

Atlantoaxial, superior radioulnar

31
Q

2 distinct convex surfaces that articulate w 2 concave surfaces

A

Condyloid joints eg. Metacarpaphalangeal units/ knuckle joints

32
Q

Wrist joint

A

Ellipsoid joint

33
Q

Carpometacarpal of thumb

A

Saddle joint

34
Q

Shoulder and hip joints

A

Ball and socket joints

35
Q

Stability of joint depends on 3 main factors

A

SHAPE, SIZE and arrangement of the articular surfaces;ligaments and the TONE of muscles around the joint

36
Q

Cord or band of connective tissue uniting two structures

A

Ligament

37
Q

Surrounds a tendon, reduce friction bet tendon and its surroundings

A

Synovial sheath

38
Q

Lubricating device consisting of a closed fibrous sac lined w delicate smooth membrane

A

Bursa

39
Q

Form of connective tissue in w/c cells and fibers are embedded in a gel like matrix ( firmness and resilience)

A

Cartilage

40
Q

High proportion ofamorphous matrix, incapable of repair when fractured

A

Hyaline cartilage

41
Q

Joint discs have a poor blood supply and therefore do not repair thmselves when damaged

A

Temporomandibukar joint
Stenoclavicular joint
Knee joint

42
