3. Nervous
4. Muscle

Question 2

Epithelial Tissue

Answer 2

Sheets of cell that cover a body surface or cavity or make up glands

Question 3

Lining Epithelium

Answer 3

Epithelial tissues that makes up skin and that lines cardiovascular, digestive, and respiratory cavities

Question 4

Answer 4

Epithelial tissues that make up glands

Question 5

5 Special Characteristics of Epithelial tissues

Answer 5

1. Polarity
2. Specialized contacts
3. Supported by connective tissues
4. Avascular but innervated
5. Regenerate

Question 6

Simple Squamous

Answer 6

Single layer of flat cells (found in lung air sacs, blood vessels, lymphatic vessels)

Question 7

Simple Cuboidal

Answer 7

Single Layer of cube-like cells (found in Kidney tubules, ducts of small glands, and ovary surface)

Question 8

Simple Columnar

Answer 8

Single layer of column-like cells (found in Digestive tract, gallbladder, uterine tubes, parts of uterus)

Question 9

Pseudostratified Columnar

Answer 9

Columnar cells of varying heights (found in ducts of large glands and the trachea)

Question 10

Stratified Squamous

Answer 10

Multi-layered flat cells (lines esophagus, mouth, and vagina and makes up the epidermis of skin

Question 11

Transitional

Answer 11

Cells that are varied in shape and can expand and contract (Lines uterus, urinary bladder, and part of the urethra)

Question 12

Endocrine Glands

Answer 12

Release hormones, ductless, exocytosis directly into blood

Question 13

Exocrine glands

Answer 13

Release sweat, oils, saliva, and bile, have ducts, Merocrine or Holocrine releases

Question 14

Merocrine

Answer 14

Releasing of cell contents through exocytosis

Question 15

Holocrine

Answer 15

Releasing of cell contents by the cell rupturing

Question 16

What are the 4 functions of connective tissues?

Answer 16

1. Binding/support
2. Protection
3. Insulation
4. Transportation

Question 17

Characteristics of connective tissue

Answer 17

Form from mesenchyme and mostly made up of a nonliving “extracellular matrix”

Question 18

Mesenchyme

Answer 18

An embryonic tissue

Question 19

Ground substance

Answer 19

Substance surrounding connective tissue cells which contains the fibers

Question 20

Connective tissue fibers

Answer 20

Provide support to the tissues

Question 21

3 types of connective tissue fibers

Answer 21

Collagen
Elastic
Reticular

Question 22

Loose Connective Tissue function and 3 types

Answer 22

Few fibers, supports and stores

Areolar
Adipose (fat)
Reticular

Question 23

3 types of Dense Connective tissues

Answer 23

Dense Regular
Dense Irregular
Elastic

Mainly fibers (tendons, ligaments, surrounds organs, dermis of skin)

Question 24

Example of Dense Regular connective tissue

Answer 24

Tendons and Ligaments

Question 25

Example of Dense Irregular connective tissue

Answer 25

Surrounds organs and dermis of skin

Question 26

Cartilage

Answer 26

Connective tissue strong in tension and compression, aging cells can't divide and heals slowly

Question 27

Bone

Answer 27

Connective tissue with rocklike hardness, support + Protection, fat storage, blood cell formation

Question 28

Blood

Answer 28

Connective tissue that transports oxygen and nutrients through the body and whose "fibers" are proteins for clotting blood

Question 29

Function and locations of nervous tissues

Answer 29

Regulate and control body function (found in the brain, spine, and nerves)

Question 30

Neurons

Answer 30

Nervous tissue cell that conducts and generates electricity

Question 31

Supporting Cell

Answer 31

Supports, insulates, and protects neurons

Question 32

Muscle Tissue

Answer 32

Well-Vascularized tissue used for movement

Question 33

3 types of muscle tissue and their locations

Answer 33

Skeletal: Attaches to skeleton (Voluntary movement) Cardiac: Makes up heart (involuntary movement) Smooth: Walls of hollow organs (involuntary movement)

Question 34

What are the 3 steps of tissue repair

Answer 34

1, Inflammation 2. Organization 3. Regeneration and Fibrosis

Question 35

Give an example of a tissue that repair well and readily and one that does not

Answer 35

Repairs well: Epithelial, bone, areolar connective, dense irregular connective Repairs poorly: Skeletal Muscle and cartilage
