25
Q

Impermeable barrier because adjacent plasma membrane proteins join producing a zipper-like fastening

A

Tight Junction

26
Q

Forms when two adjacent plasma membrane channels join

A

Gap Junction

27
Q

Gives strength but allows ions, sugars, and small molecules to pass between two molecules

A

Gap Junction

28
Q

Also known as desmosomes; adjacent plasma membrane do not touch each other but are held together by intercellular filaments firmly attached to cytoplasmic plaques

A

Adhesion Junction

29
Q

Kinds of junctions in order

A

Tight, adherens, desmosome, gap, hemidesmosome

30
Q

noncellular material that varies in consistency from solid to semifluid to fluid

A

Matrix

31
Q

Separated by matrix

A

Connective Tissue

32
Q

Functions of Connective Tissues

A

Binds organs together, provides support/protection, produces blood cells, stores fat

33
Q

Three types of matrix

A

Collagen Fiber, Reticular Fiber, Elastic Fiber

34
Q

white, contains collagen that gives flexibility and strength

A

Collagen Fiber

35
Q

very thin collagen fibers that are highly branched and form delicate supporting networks

A

Reticular Fiber

36
Q

yellow, and contains elastin that gives elasticity

A

Elastic Fibers

37
Q

Kinds of connective tissue

A

Fibrous, Adipose, Reticular Connective, Cartilage, Bones, Blood

38
Q

has fibroblast that has jelly like matrix

A

Fibrous connective tissue

39
Q

Two kinds of fibrous connective tissue

A

Loose, Dense

40
Q

Has large fibroblasts that store fat, used for energy, insulation, and organ protection

A

Adipose Tissue

41
Q

serves as the supporting meshwork of lymphatics

A

Reticular Connective Tissue

42
Q

separated by a matrix that is solid yet flexible; its cells lie in small chambers called lacunae; lacks direct blood supply so it heals very slow

A

Cartilage

43
Q

Three types of cartilage

A

Hyaline, Fibrocartilage, Elastic

44
Q

most common type of cartilage; contains very fine collagen fibers; found in nose, ends of long bones, ribs, and rings, in the walls of RT; fetal skeleton

A

Hyaline Cartilage

45
Q

matrix has strong collagen fibers and found in areas that could withstand pressure and tension such as pads between vertebrae in backbones and wedges in knee joints

A

Fibrocartilage

46
Q

type of cartilage that has more elastin; more flexible; ex us framework of outer ear

A

Elastic Cartilage

47
Q

most rigid connective tissue; has very hard matrix of inorganic salts for rigidity, deposited around protein fibers esp. collagen fibers for elasticity

A

Bones

48
Q

Kinds of Bones

A

Compact, Spongy

49
Q

makes up the shaft of long bones; has cylindrical units called osteons (Haversian system)

A

Compact Bone

50
Q

found in the ends of long bones; has numerous bony bars and plates separated by irregular spaces

A

Spongy Bone

51
Q

Functions of Blood

A

1.) Transports nutrients and oxygen to tissue fluids
2.) Removes Co2 and waste products
3.) Helps distribute heat and fluids/ions, and for pH balance
4.) Gives protection

52
Q

Composed of cells called muscle fivers which contain myosin and actin filaments for movement

A

Muscle Tissue

53
Q

3 Types of muscle tissue

A

Skeletal, Smooth, Cardiac

54
Q

Has nerve cells called neurons found in the brain and spinal cord

A

Nervous Tissue

55
Q

Nerve cells

A

Neurons

56
Q

fibers Bounded by connective tissues

A

Nerves

57
Q

Functions of nervous sytem

A

sensory input, integration of data, motor output

58
Q

What are Neurons composed of

A

Axon, Dendrites

59
Q

Motor output/Send signals away

A

Axons

60
Q

Motor input; Sends signals into the neuron; sensory input

A

Dendrites
