Mastering A & P Histology

Question 1

2 basic components of a tissue

Answer 1

1. discrete population of cells that relate in structure and fucnito
2. Has an ECM (extracellular matrix)

Question 2

4 main types of tissues

Answer 2

1. Epithelium
   2, Connective
2. Muscle
3. Nervous

Question 3

Epithelium tissues

Answer 3

• Consists of sheets of cells that are tightly packed together with little visible ECM.
• Covers all the linings on the body’s surface and cavities
• Specialised Epithelium cells form glands, which are groups of cells that manufacture and secrete or release a product such as sweat salvia or chemical messenger such as hormones

Question 4

Connective tissue

Answer 4

-Characterised by its extensive Extracellular matrix
-Functions in protection support and transport

Question 5

Muscle Tissue

Answer 5

composed of cells that can contract and generate force with little ECM in between them.

Question 6

Nervous Tissue

Answer 6

Unique ECM
Composed of cells that can generate, receive or send messages and other cells that support this activity.

Question 7

2 main components of ECM

Answer 7

1. Ground Substance
2. Protein fibres

Question 8

Functions of ECM

Answer 8

1. Giving strength to tissues to resist tensile and compressive forces.
2. Directing cells to be in the correct place in the tissue
3. Regulating development, mitotic activity and survival of cells
4. holding cells in their proper places

Question 9

Ground Substance

Answer 9

the amorphous substance of the ECM
-contains water proteoglycans glycosaminoglycans and other substances.

Question 10

Glycosaminoglycans (GAG)
