A&p Lecture Exam 2

Front 1

Epithelial tissue

Back 1

Covers body surfaces and lines hollow organs, body cavities, ducts, and forms glands

Front 2

Connective tissue

Back 2

Protects, supports, and binds organs. Stores energy as fat, provides immunity.

Front 3

Muscular tissue

Back 3

Generates the physical force needed to make body structures move and generate body heat

Front 4

Nervous tissues

Back 4

Detect changes in body and responds by generating nerve impulses

Front 5

Tight junctions

Back 5

Fuses and seals.

Prevents leakage.

Found in stomach, intestines, and bladder.

Front 6

Adherens junctions

Back 6

Made up of a dense layer of proteins called plaque.

Connects microfilaments of 2 cells.

Front 7

Desmosomes

Back 7

It connects intermediate filaments of 2 cells.

Prevents separation.

Located in epidermis and heart.

Front 8

Hemidesmosomes

Back 8

Anchors cells to the basement membrane.

Locations in muscle, nerve, blood vessel

Front 9

Gap junctions

Back 9

Connect side by side cells via tiny fluid filled tunnels called connexons.

It is 2 way traveling.

Front 10

3 major functions of epithelial tissue

Back 10

Protection, secretions, movement

Front 11

Apical (free) surface

Back 11

Faces the body surface, body cavity, lumen, or duct

Front 12

Basal surface

Back 12

Opposite of apical layer and adhere to basement membrane

Front 13

Is epithelial tissue vascular or avascular? Innervated or noninnervated?

Back 13

Avascular and Innervated

Front 14

Squamous cell functions

Back 14

Rapid passage of substances

Front 15

Cuboidal cell functions

Back 15

Secretion and absorption

Front 16

Columnar cell functions

Back 16

Secretion and absorption

Front 17

Transitional cell functions

Back 17

Change shape from flat to cuboidal

Front 18

Simple squamous epithelium

Back 18

Single layer of cells.

Founds at sites for filtration or diffusion.

Ex: Lung tissue

Front 19

Simple cubodial epithelium

Back 19

Found in thyroid gland and kidneys.

Functions in secretion and absorption.

Front 20

Simple columnar epithelium

Back 20

Nonciliated and ciliated

Front 21

Psuedostratified columnar epithelium

Back 21

Appears to have several layers.
