Module 1 Test

Portage learning BIOD 152 Module 1 Test. Questions might vary but answers are the teachers answers.

Test

1. THIS IS A BUNDLE OF AXONS FOUND IN THE PERIPHERAL NERVOUS SYSTEM.

a. NERVES.

2. THIS PART OF THE AUTONOMIC NERVOUS SYSTEM INCREASES DIGESTION.

a. PARASYMPATHETIC.

3. THE DORSAL ROOT OF A NERVE CONTAINS WHAT TYPE OF NEURONS?

a. SENSORY (AFFERENT).

4. THIS PART OF A NEURON CONDUCTS NERVE IMPULSES AWAY FROM THE CELL

BODY.

a. AXON.

5. A NEURON GOING TO THE BICEP OF THE FOREARM IS PART OF THE:

a. PERIPHERAL NERVOUS SYSTEM & SOMATIC SYSTEM.

6. THE NEURON PICTURED BELOW IS BEST DESCRIBED AS:

a. BIPOLAR.

7. TRUE OR FALSE: NEURONS DO NOT PHYSICALLY TOUCH ONE ANOTHER.

a. TRUE.

8. DESCRIBE THE FUNCTION & RELEASE OF NEUROTRANSMITTERS.

a. NEUROTRANSMITTERS ARE CHEMICALS STORED INSIDE SECRETORY

VESICLES (AXON TERMINAL VESICLES) AT THE END OF THE AXON

TERMINALS.

b. WHEN NEUROTRANSMITTERS ARE RELEASED BY THE AXON TERMINAL

VESICLES, THEY CARRY THE TRANSMISSION OF THE NERVE IMPULSE

FROM ONE NEURON TO ANOTHER.

9. AN AFFERENT NEURON CARRIES INFORMATION:

a. FROM THE PERIPHERAL TO THE CENTRAL NERVOUS SYSTEM.

10.A PRESYNAPSE NEURON WOULD BE FOUND:

a. BEFORE THE SYNAPSE.

11.WHAT IS THE LOCATION & FUNCTION OF SATELLITE CELLS?

a. PERIPHERAL NERVOUS SYSTEM.

b. REGULATION OF ENVIRONMENT OF NEURON CELL BODIES.

12.A PATIENTS’ LEFT THUMB WAS SEVERED IN A COOKING ACCIDENT & THEN

REATTACHED DURING SURGERY. WOULD THE PATIENT BE EXPECTED TO

REGROW AXONS IN THEIR THUMB? WHY OR WHY NOT?

a. YES, PERIPHERAL NERVES CAN REGENERATE THE LENGTH OF THE

AXON THROUGH AXONAL REGENERATION BECAUSE OF THE GROWTH

OF SCHWANN CELLS AHEAD OF AXON.

13.NAME & DESCRIBE WHAT IS OCCURRING IN THE NEURON CELL MEMBRANE IN

SECTION 2 OF THE DIAGRAM. INCLUDE THE CHARGE OF THE MEMBRANE

DURING THIS PHASE.
