55
The human body has more than ________ muscles, which make up half of a person's body weight.
650
56
Humans have _______ different kinds of muscle
three
57
three different kinds of muscle
cardiac muscle cell
skeletal muscle cell
smooth muscle cell
58
are connected to bones by tough, cord-like tissues called Tendons, which allow the muscles to pull on bones..
Skeletal muscle
59
is a band of connective tissue that connects muscle to bone
tendon
60
are a place where two or more bones meet. It is a place where bones can move in relation to each other.
Joints
61
Function of joints
They make the skeleton flexible
62
They attached to each other by ________ or ________
ligaments, cartilage
63
Immovable:connect bones, no movement. (skull and pelvis).
Fibrous
64
slightly movable, bones are attached by cartilage, a little movement (spine or ribs).
Cartilaginous
65
freely movable, much more movement than cartilaginous joints. Cavities between bones are filled with synovial fluid. This fluid helps lubricate and protect the bones.
Synovial
66
Type of Joints
Fibrous joints
Cartilaginous Joints
Synovial Joints
67
Joint with a rounded, ball-like end of one bone fitting into a cuplike socket of another bone
Ball-and-socket joint
68
Joint in which the bones are connected by cartilage
Cartilaginous joint
69
Movement of a limb in a circular motion.
Circumduction
70
Oval-shaped end of one bone fitting into a similarly oval-shaped hollow of another bone
Condyloid joint
71
Types of Synovial Joints
Hinge
Ball and Socket
Gliding
Saddle
72
A hinge joint allows EXTENSION and RETRACTION of an APPENDAGE. (Elbow, Knee)
Hinge
73
allows for RADIAL movement in almost any direction. They are found in the hips and shoulders. (Hip, Shoulder)
Ball and Socket
74
bones SLIDE PAST EACH OTHER. Mid-carpal and mid-tarsal joints are examples. (Hands, Feet)
Gliding
75
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)
Saddle
76
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.
Fibrous joints
77
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.
Cartilaginous Joints
78
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 .
Cartilage
79
Strong fibers that JOIN BONES TOGETHER; usually NON ELASTIC and white, but some are yellow and more stretchy .
LIGAMENTS
80
function of ligaments
connect bone to bone
provide stability by preventing too much movement
