Q

Stratified Columnar Epithelium:

A
  • Rare in body
  • Location: vas deferens and pharynx
17
Q

Mitosis: Prophase

A
  • Begins karyokinesis
  • Nuclear membrane begins to disappear
  • Chromosomes become visible
18
Q

Mitosis: Metaphase

A
  • Chromosomes line up on equatorial
  • Spindle attaches to chromosomes at centrosphere
19
Q

Mitosis: Anaphase

A
  • Chromosomes separate and move to opposite poles
  • Cytokinesis begins
20
Q

Mitosis: Telophase

A
  • Cytokinesis and Karyokinesis complete
  • Nuclear membrane reappears
  • Chromosomes become less visible
21
Q

Hyaline Cartilage:

A
  • Contains chondrocytes
  • Makes template for most bone
21
Q

Mesothelium location:

A

serous membrane

22
Q

Elastic Cartilage:

A
  • Contains chondrocytes
  • Strong and Flexible (nose and ears)
23
Q

Compact bone:

A
  • Osteocytes
24
Q

Blood is the only…

A

liquid connective tissue

25
Q

Three types of muscle tissue:

A
  • Cardiac (intercalated discs)
  • Skeletal
  • Smooth
26
Q

Nervous tissue:

A
  • Multipolar nerve cells have multiple dendrites
  • A cell body that contains the nucleus, and a single axon
  • Nerve impulses flow from dendrites to cell body to axon
