Question 1

What are the 2 fluid connective tissues?

Answer 1

Blood and lymph

Question 2

What is histology?

Answer 2

The study of tissues — groups of similar cells that work together to perform specialized tasks.

Question 3

What are the four primary tissue types?

Answer 3

Epithelial, connective, muscular, nervous.

Question 4

What are the two criteria used to classify epithelial tissue?

Answer 4

(1) Number of cell layers (simple vs stratified) (2) Shape of the cells (squamous, cuboidal, columnar).

Question 5

Functions of epithelial tissue?

Answer 5

Protection, support, absorption, transportation, secretion.

Question 6

‘Simple’ vs ‘Stratified’ epithelium?

Answer 6

Simple = one cell layer; Stratified = multiple cell layers.

Question 7

‘Squamous’ vs ‘Cuboidal’ vs ‘Columnar’?

Answer 7

Squamous = flat; Cuboidal = cube-shaped; Columnar = tall and column-like.

Question 8

Identify this tissue: Simple squamous epithelium

Answer 8

Simple squamous epithelium (single layer of flat cells).

Question 9

Identify this tissue in kidney tubules

Answer 9

Simple cuboidal epithelium.

Question 10

Identify this tissue in intestinal lining

Answer 10

Simple columnar epithelium.

Question 11

What is unique about pseudostratified columnar epithelium?

Answer 11

It appears stratified but is not — pseudostratified columnar with cilia.

Question 12

General features of connective tissue?

Answer 12

Widely spaced cells, separated by fibers and ground substance. Most abundant and variable tissue.

Question 13

Functions of connective tissue?

Answer 13

Connects organs, provides support & protection, energy storage, heat production, movement, transport of materials.

Question 14

Major categories of connective tissue?

Answer 14

Connective tissue proper (loose, dense), fluid (blood, lymph), supporting (cartilage, bone).

Question 15

Identify this connective tissue: Areolar tissue

Answer 15

Areolar tissue — surrounds blood vessels, nerves, organs.

Question 16

Identify this connective tissue: Adipose tissue

Answer 16

Adipose tissue — stores fat, provides insulation, cushions organs.

Question 17

Identify this connective tissue: Hyaline cartilage

Answer 17

Hyaline cartilage — supports, cushions, resists compression.

Question 18

Identify this connective tissue: Elastic cartilage

Answer 18

Elastic cartilage — maintains shape, supports ear and epiglottis.

Question 19

Identify this connective tissue: Fibrocartilage

Answer 19

Fibrocartilage — resists compression, strong support.

Question 20

Identify this connective tissue: Compact bone

Answer 20

Compact bone — solid, supports and protects, mineral storage.

Question 21

Identify this connective tissue: Blood

Answer 21

Blood — fluid tissue composed of plasma and formed elements.

Question 22

What are the three types of muscle tissue?

Answer 22

Skeletal, cardiac, smooth.

Question 23

Which muscle types are striated?

Answer 23

Skeletal and cardiac.

Question 24

Identify this muscle type: Skeletal muscle

Answer 24

Skeletal muscle — striated, voluntary, multinucleate fibers.

Question 25

Identify this muscle type: Smooth muscle

Answer 25

Smooth muscle — non-striated, involuntary, single nucleus.

Question 26

Identify this muscle type: Cardiac muscle

Answer 26

Cardiac muscle — striated, involuntary, intercalated discs.

Question 27

What are the two main cell types in nervous tissue?

Answer 27

Neurons and glial cells.

Question 28

Function of nervous tissue?

Answer 28

Internal communication — brain, spinal cord, nerves, ganglia.

Question 29

Identify these large cells with long processes

Answer 29

Neurons (with supporting glial cells).
