Biology

Question 1

The most abundant glial cell and form the blood brain barrier. They also help recycle NT and provide blood supply to the CNS neurons

Answer 1

Astrocytes

Question 2

Form the myelin sheath in the CNS

Answer 2

Oligodendrocytes

Question 3

Have the same functions as astrocytes but instead help PNS neurons

Answer 3

Satellite cells

Question 4

Produce CSF which cushions the CNS

Answer 4

Ependymal cells

Question 13

Excitatory postsynaptic nt of the sympathetic ns

Answer 13

Epinephrine

Norepinephrine

Question 14

Excitatory nt of the brain involved in reward motivated behavior

Answer 14

Dopamine

Question 15

Inhibitory nt of the brain involved in mood, appetite, sleep and learning

Increases contraction of the gastrointestinal tract in response to food intake

Answer 15

Serotonin

Question 16

Diverse roles involved in a wide range of brain functions

Answer 16

Short chain aa such as substance p

Question 17

Causes smooth muscle relaxation. In blood Vessels, this results in vasodilation which leads to decreased bp

Unlike other nts it is synthesized and released on demand rather than stored in vessicles

Answer 17

Nitric oxide

Pons and cerebellum

Question 23

Myencephalon gives rise to

Answer 23

Medulla oblongata

Question 24

Exploitation competition

Answer 24

Indirect. Occurs when common source is depleted

Question 25

Interference competition

Answer 25

Establishment of other individuals who compete for a mutual resource is prevented

Ex: allelopathy

Question 26
