Q

what do holocrine glands secrete

A

secrete disintegrating cells, with the contents becoming the secretion

24
Q

what does an apocrine gland secrete

A

the apical surface of the gland

25
Q

what are the functions of connective tissue

A

protection, support, storage, bidning, transport, and immunity

26
Q

what three things do connective tissue consist of

A

specialized cells, protein fibers, and ground substance

27
Q

what is the purpose of resident cells

A

support, maintain, repair

28
Q

what is the purpose of wandering cells

A

immune protection, repair

29
Q

what three fibers make up connective tissue

A

collagen, elastic, reticular

30
Q

collagen

A

an abundant protein, flexible but strong, thickets of connective tissue fibers

31
Q

elastic

A

elastin protein, stretchy, thinner than collagen

32
Q

reticular

A

forms a net, made of a protein similar to collagen

33
Q

mesenchyme

A

first connective tissue to emerge, all other tissues derive from it

34
Q

definition of tissue

A

group of similar cells with common function

35
Q

definition of histology

A

study of tissues and relationships within the organs

36
Q

hypertrophy

A

increase in cell size

37
Q

atrophy

A

decrease in cell size

38
Q

hyperplasia

what are tissues composed of

A

cells and matrix

41
Q

what is matrix

A

nonliving intercellular substance

42
Q

define muscle tissue

A

specialized cells that respond to stimulation. often elongated.

43
Q

what are the three types of muscle

A

skeletal, smooth, and cardiac

44
Q

skeletal muscle

A

striated, peripheral multi nuclei. voluntary.

46
Q

what does smooth muscle form

A

visceral organs, blood vessel walls

47

what type of muscle forms sheets

A

smooth muscle

51
Q

what does smooth muscle do

A

propel substances or objects along internal passageways

52
Q

function of epithelial tissue
