Q

Define “neuroglia”

A

The cells that support neurons. They attach to neurons and vascular structure, they supply neurons with nutrients so they don’t die

A

Provides us with movement

44
Q

What does epithelial tissue do?

A

Covers and protects the body

45
Q

A

Connective

46
Q

The brain and spinal cord

47

A

All the nerves in your body

48
Q

What are the 2 main functions of nervous tissue?

A

Sensing stimuli and sending impulses (signals) throughout the body

49

A

Cells that provide protection, support, insulation and tethering to neurons

49
Q

Describe what muscle tissue looks like

A

Long parallel tubes with stripes with purple dots

50
Q

Is skeletal muscle tissue voluntary or involuntary?

A

Voluntary, you use your brain to control it

51
Q

Is cardiac muscle voluntary or involuntary?

A

Involuntary, it works without you thinking about it

52
Q

What does cardiac tissue look like?

A

Variety of striped tubes with fewer purple spots than skeletal muscle, darker colours at the edges where they connect. Branching structure

53
Q

What does smooth muscle tissue look like?

A

Closely packed smooth sheets without stripes. Squished rectangles sorta

54
Q

Q

What does “invagination” mean?

A

The action or process of being turned inside out or folded back on itself to form a cavity or pouch

57
Q

What is the glandular epithelium?

A

Forms glands and secretes hormones and other stuff

58
Q

True or false: epithelial tissues are avascular

A

True, they do not have a blood supply. They get their nutrients from the blood supply of neighboring connective tissues

59
Q

Describe what a squamous cell looks like

Flat, squished “scales” with a purple nucleus in the middle

60
Q

What do squamous cells do?

A

Protection and allow the transfer of things

61
Q

What do cuboidal cells do?

A

Absorb nutrients and produce secretions

62
Q

What do columnar cells do?

Absorb nutrients, secrete and cushion underlying tissues

63
Q

Which type of epithelial cells require the fewest resources to make?

A

Squamous

64
Q

What is the top part of epithelial tissue called?

A

Apical (which is exposed to either the cavity it is lining or the outside world)

65
Q

What is the bottom surface of epithelial tissue called?

A

Basal (connecting it to the basement membrane)

66
Q

True or false: most epithelial tissue is selectively permeable

A

True
