55
Q

The human body has more than ________ muscles, which make up half of a person’s body weight.

A

650

56
Q

Humans have _______ different kinds of muscle

A

three

57
Q

three different kinds of muscle

A

cardiac muscle cell
skeletal muscle cell
smooth muscle cell

58
Q

are connected to bones by tough, cord-like tissues called Tendons, which allow the muscles to pull on bones..

A

Skeletal muscle

59
Q

is a band of connective tissue that connects muscle to bone

A

tendon

60
Q

are a place where two or more bones meet. It is a place where bones can move in relation to each other.

A

Joints

61
Q

Function of joints

A

They make the skeleton flexible

62
Q

They attached to each other by ________ or ________

A

ligaments, cartilage

63
Q

Immovable:connect bones, no movement. (skull and pelvis).

A

Fibrous

64
Q

slightly movable, bones are attached by cartilage, a little movement (spine or ribs).

A

Cartilaginous

65
Q

freely movable, much more movement than cartilaginous joints. Cavities between bones are filled with synovial fluid. This fluid helps lubricate and protect the bones.

A

Synovial

66
Q

Type of Joints

A

Fibrous joints
Cartilaginous Joints
Synovial Joints

67
Q

Joint with a rounded, ball-like end of one bone fitting into a cuplike socket of another bone

A

Ball-and-socket joint

68
Q

Joint in which the bones are connected by cartilage

A

Cartilaginous joint

69
Q

Movement of a limb in a circular motion.

A

Circumduction

70
Q

Oval-shaped end of one bone fitting into a similarly oval-shaped hollow of another bone

A

Condyloid joint

71
Q

Types of Synovial Joints

A

Hinge
Ball and Socket
Gliding
Saddle

72
Q

A hinge joint allows EXTENSION and RETRACTION of an APPENDAGE. (Elbow, Knee)

A

Hinge

73
Q

allows for RADIAL movement in almost any direction. They are found in the hips and shoulders. (Hip, Shoulder)

A

Ball and Socket

74
Q

bones SLIDE PAST EACH OTHER. Mid-carpal and mid-tarsal joints are examples. (Hands, Feet)

A

Gliding

75
Q

This type of joint occurs when the touching surfaces of two bones have both concave and convex regions with the shapes of the two bones complementing one other and allowing a wide range of movement. (Thumb)

A

Saddle

76
Q

In this type of joints the bones are joined together by means of fibrous tissue.
There is no movement between the bones such as the sutures of the skull and the teeth in their sockets.

A

Fibrous joints

77
Q

joints where the articular surfaces of the bones forming the joints are attached to each other by means of white fibrocartilaginous discs and ligaments which allow only a LIMITED DEGREE OF MOVEMENT.

A

Cartilaginous Joints

78
Q

flexible CONNECTIVE TISSUE found in many areas in the bodies of humans , including the joints between bones .
THe main Function is to REDUCE FRICTION in the joint with movement .

A

Cartilage

79
Q

Strong fibers that JOIN BONES TOGETHER; usually NON ELASTIC and white, but some are yellow and more stretchy .

A

LIGAMENTS

80
Q

function of ligaments

A

connect bone to bone
provide stability by preventing too much movement
