Q

Glandular epithelia

A

Secretion

19
Q

Why are endocrine glands ductless?

A

Because their glands do not have ducts to carry product to a surface

20
Q

Which tissue is most abundant?

A

Connective

21
Q

What are the functions of connective tissue?

A

Connection (connects tissue), support, protection, fat storage, transportation

22
Q

Types of connective tissues

A

Hard (bone), Semihard (cartilage), liquid (blood)

23
Q

Which tissue is most well vascularized?

A

Connective tissue

24
Q

Loose connective tissue

A

Areolar, adipose, reticular

25
Q

Types of cartilage tissue

A

Hyaline, fibrocartilage, elastic

26
Q

Nervous tissue

A

Makes up spinal cord, brain, nerves

27
Q

Types of nervous tissue cells

A

Neurons, neuroglia

28
Q

Neurons functions

A

Transport signals, do not regenerate

29
Q

Neuroglia functions

A

Protects and supports neurons, can regenerate

30
Q

Muscle tissue

A

Composed of cells (fibers) that contract for movement

31
Q

Types of muscle tissue

A

Skeletal, smooth, cardial

32
Q

Skeletal muscle tissue

A

Voluntary and stratified

33
Q

Smooth muscle tissue

A

Involuntary and nonstratified

34
Q

Cardial muscle tissue

A

Involuntary and stratified

35
Q

Tissue repair

A

Regeneration: replacing tissue via mitosis

36
Q

Fibrosis

A

Replacing tissue (injured) with fibrous connective tissue (scar tissue)

37
Q

Keloid

A

Excessive fibrosis

38
Q

Tissue repair process

A
  1. Wound 2. Clot and scab 3. Tissue repair begins 4. Scar tissue forms 5. Epithelial tissue multiplies 6. Scab detaches
39
Q

Visceral

A

Filled with fluid

40
Q

Membranes

A

Cover surfaces, line body cavities, surround organs

41
Q

Epithelial membranes

A

Cutaneous, mucous (exterior, mouth), serous (not exterior, pleura, pericardium, peritoneum)

42
Q

Connective membranes

A

Synovial (joints), periosteum (surrounds bone), perichondrium (cover cartialige), meninges (brain and spinal cord), fascia (covers muscle)

43
Q

Peritoneum, pleura, pericardium

A

Parietal and visceral
