17
Q

Match the description with the correct term: Neuron that conveys information from a receptor to the CNS

A

Sensory neuron

18
Q
  1. Damage to dendrites would interfere with a neuron’s ability to:
    a) receive input
    b) make proteins
    c) conduct nerve impulses to another neuron
    d) release neurotransmitters
    e) form myelin
A

a) receive input

19
Q
  1. The type of cell that produces myelin sheaths around axons in the CNS is the

a) astrocyte
b) myelinocyte
c) Schwann cell
d) oligodendrocyte
e) microglia

A

d) oligodendrocyte

20
Q

What are Neuroglia?

A

Cells that are smaller than neurons, and can readily multiply and divide to fill in brain areas, a power that neurons do not possess

Neuroglia make up half the volume of CNS, and do not function to conduct nerve impulses.

21
Q

What type of neuroglia are star shaped connective tissue cells and help form the blood-brain barrier?

A

Astrocytes
- Star shaped connective tissue cells
- link nerve cells to blood vessels
- help form the blood-brain barrier by wrapping round brain capillaries

22
Q

What type of neuroglia:
- have an adventitial structure of the central nervous system
- capable of creating myelin

A

Oligodendrocytes

23
Q

What type of neuroglia:
- Are migratory
- Act as phagocytes of waste products from the nervous system

A

Microglia

24
Q

What type of neuroglia:
- Form the membrane, lining the cerebral ventricles
- The ventricles are interconnected, fluid filled chambers within the brain and central canal of the spine

A

Ependymal

25
Q

What type of neuroglia:
- Surround the axons of the peripheral nerves
- Forming the myelin sheath of myelinated nerve fibers and also providing support for nonmyelinated nerves

A

Schwann cell

26
Q

What type of neuroglia:
- Are neuroglial cells surrounding the cell body of a neuron in the spinal, cranial and autonomic ganglia

A

Satellite cells

27
Q

A bundle of axons in the CNS is:

a) a tract
b) a nucleus
c) a mixed nerve
d) a ganglion
e) an enteric plexus

A

a) a tract

28
Q

In a resting neuron:

a) there is a high concentration of potassium ions outside the cell

b) negatively charged ions move freely through the plasma membrane

c) the sodium-potassium pumps help maintain the low concentration of sodium ions inside the cell

d) the outside surface of the plasma membrane has a negative charge

e) the plasma membrane is highly permeable to sodium ions

A

c) the sodium-potassium pumps help maintain the low concentration of sodium ions inside the cell

29
Q

Place the following events in the correct order of occurrence:

  1. Voltage-gated sodium channels open and permit sodium ions to rush inside the neuron
  2. The sodium/potassium pump restores the ions to their original sites
  3. A stimulus of threshold strength is applied to the neuron
  4. The membrane polarisation changes from negative to positive
  5. Voltage-gated potassium channels open and potassium flows out of the neurons.
A

3,1,4,5,2

30
Q

If a stimulus is strong enough to generate an action potential, the impulse generated is of a constant size. A stronger stimulus cannot generate a larger impulse. This is known as:

a) the principle of polarisation-depolarisation

b) salutatory conduction

c) the all-or-none principle

d) the principle of reflex action

e) the absolute refractory period

A

c) the all-or-none principle

31
Q

The diencephalon is composed of the

a) medulla, pons and hypothalamus
b) midbrain, hypothalamus and thalamus
c) cerebellum and midbrain
d) medulla, pons and midbrain
e) hypothalamus and thalamus (& pineal
Gland)

A

e) hypothalamus and thalamus (& pineal
Gland)

32
Q

Which part of the brain contains the centres that control the heart rate and breathing rhythm?

a) medulla
b) midbrain
c) cerebellum
d) thalamus
e) pons

A

a) medulla
