Hyaline Cartilage
28
More collagen than hyaline and connects structures subjected to great pressure
Fibrocartilage
29
Contains elastic and collagen and it provides rigidity with even more flexibility than hyaline

Characteristics of __________ - Forms wall of the hollow organs - Movement of food in the digestive tract and emptying urinary bladder
Smooth Muscle
34
Muscle of the heart and is responsible for pumping blood and this is INVOLUNTARY CONTROL
Cardiac Muscle
35
Controls and coordination of body actions
Nervous Tissue
36
Impulse conduction
Neurons

DENDRITES — __________ AXON — transfer or sends
receives
38
Thin sheets or layers of tissue that cover a structure or lines a cavity.
Tissue membrane
39
Consist of kinds of epithelium resting on a thick layer of connective tissue
Mucous membrane
40
Consist of simple squamous epithelium resting on a loose connective tissue and lines pleural, peritoneal, and pericardial cavities
Serous membrane
41
Consist of modified connective tissue cells and lines freely on movable joints
Synovial fluid
