1. Epithelial
2. Connective
3. Muscular
4. Nervous

Question 4

Epithelial Tissue

Answer 4

• Contains cells that are tightly packed together

- Little to no extracellular matrix space

Question 5

Answer 10

1. Fibrous connective tissue
2. Cartilage
3. Bone
4. Blood

Question 11

Two types of fibrous connective tissue

Answer 11

1. Loose Connective Tissue

2. Dense Connective Tissue

Question 12

Types of Loose connective tissue

Answer 12

1. Areolar
2. Adipose
3. Reticular

Question 13

Dense connective tissue

Answer 13

Mainly compacted collagen fibers

-Tendons & ligaments

Question 14

Cartilage

Answer 14

Composed of chondrocytes that have a lot of matrix space that is flexible
-Little blood flow

Question 15

What gives Cartilage its characteristic

Answer 15

Matrix space and substances

Question 16

Three types of cartilage

Answer 16

1. Hyaline
2. Elastic
3. Fibrocartilage

Question 17

Bone

Answer 17

Type of connective tissue and contains osteocytes
- A lot of matrix space which is filled with calcium phosphate salt and collagen fibers - this gives bones its hard but yet slightly flexible characteristic

Question 18

Blood

Answer 18

Unique tissue because it is a fluid

Question 19

Types of blood

Answer 19

• Red blood cells
• White blood cells
• Plasma (Blood plasma is the matrix)

Question 20

Muscular tissue

Answer 20

The cells of muscle tissue are unique because they can go through contraction

Question 21

Matrix of Muscular tissue

Answer 21

Little to no matrix space

Question 22

Three types of muscle tissue

Answer 22

1. Skeletal muscle
2. Smooth muscle
3. Cardiac Muscle

Question 23

Skeletal Muscle

Answer 23

• Attached to the skeletal system

- Striated appearance and under voluntary control

Question 24

Cardiac Muscle

Answer 24

Found in the heart

-Striated appearance and under unconscious/involuntary control

Question 25

Smooth Muscle

Answer 25

Found primarily within internal organs

-Not striated and under unconscious/involuntary control

Question 26

Nervous Tissue

Answer 26

Nerve cells have a very unique shape and size

-Conduct electrical impulses as a form of communication within the body

Question 27

What is the matrix space of nervous tissue

Answer 27

Filled with support cells referred to neuroglia cells

Question 28

What are the two ways of tissue repair

Answer 28

1. Regeneration

2. Fibrous

Question 29

Regeneration of Tissue

Answer 29

Occurs when damaged/injured cells of the tissue are replaced within the same cells

Question 30

Fibrosis tissue repair

Answer 30

Occurs when the damaged/injured cells of the tissue are replaced with scar tissue
***Function is NOT maintained
