1. memory formation
2. central role in brain injury and disease
3. implicated in neurodevelopment disorders like autism and schizophrenia

Question 6

What are the four types of tissue ?

Answer 6

1. Epithelial tissue
2. Connective tissue
3. Muscle tissue
4. Nervous tissue

Question 7

What are the two most diverse tissues which are classified according to structure?

Answer 7

1. Epithelial tissue

2. Connective tissue

Question 8

Name some features of Epithelial Tissue.

Answer 8

1. it forms a lining layer on the outer and inner surfaces of organs.
2. Epithelial cells often grow and divide rapidly
3. They lack a blood supply-nutrients and o2 diffuse from the underlying tissue.

Question 9

Which tissue contains fibres within the matrix which compromise of collagen and elastin?

Answer 9

Connective Tissue- C and E

Question 10

What is the purpose of collagen?

Answer 10

It is a protein whose structure provides strength and flexibility e.g. A tendon

Question 11

What is the purpose of Elastin?

Answer 11

It is a protein with a different structure that allows for distortion and then restoration of a structures original shape. Elastin fibres allow the walls of a blood vessel to expand and recoil as blood passes.

Question 12

What are the major cell types that are found in most connective tissues?

Answer 12

1. Fibroblast- secrete extracellular fibres
2. Mast cells- secrete histamine
3. Macrophages- Engulf phagocytose,ageing cells,damaged cells and cancer cells.

Question 13

What type of tissue consists of nerve cells and associated supporting cells?

Answer 13

Nervous Tissue

Question 14

Give examples of nerve tissue.

Answer 14

1. Brain
2. Spinal cord
3. Peripheral NS

Question 15

What is the function of a neuron?

Answer 15

They are specialized to react to stimuli and to conduct impulses to various organs in the body to bring about a response.

Question 16

What tissue has the ability to contract and to conduct electrical impulses?

Answer 16

Muscle tissue

Question 17

What are the three types of muscle tissue?

Answer 17

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

Question 18

What does two or more different tissues form?

Answer 18

Organ

Question 19

What is the organ that processes digested nutrients and is the largest organ inside the body?

Answer 19

Question 22

What organ system does the trachea belong to?

Answer 22

Respiratory system

Question 23

What type of tissue forms a packing material that surrounds and protects organs by cushioning them?

Answer 23

Connective Tissue
