The Biological Perspective - Nervous System and Neurons

What are the two types of cells that make up the brain?

• The two types of cells that make up the brain are neurons and glial cells.

• The two types of cells that make up the brain are neurons and epithelial cells.

• The two types of cells that make up the brain are neurons and muscle cells.

• The two types of cells that make up the brain are neurons and adipose cells.

The function of myelin in neurons is to:

• protect the neuron

• increase the speed of nerve impulse conduction

• store neurotransmitters

• provide nutrients to the neuron

When a neuron is at rest, what is the state of the neuron?

• The neuron is actively sending signals.

• The neuron is in a polarized state.

• The neuron is depolarized.

• The neuron is hyperpolarized.

Neurons fire in an all-or-nothing manner.

• True

• False

The role of synaptic vesicles in neurons is to:

• store neurotransmitters

• transmit electrical signals

• provide structural support

• regulate ion flow

The nervous system is made up of how many primary systems?

• The nervous system is made up of 2 primary systems: the central nervous system (CNS) and the peripheral nervous system (PNS).

• The nervous system is made up of 3 primary systems: the central nervous system (CNS), the peripheral nervous system (PNS), and the autonomic nervous system (ANS).

• The nervous system is made up of 4 primary systems: the central nervous system (CNS), the peripheral nervous system (PNS), the autonomic nervous system (ANS), and the enteric nervous system (ENS).

• The nervous system is made up of 1 primary system: the central nervous system (CNS).

What are the two divisions of the autonomic nervous system?

• The two divisions of the autonomic nervous system are the sympathetic nervous system and the parasympathetic nervous system.

• The two divisions of the autonomic nervous system are the central nervous system and the peripheral nervous system.

• The two divisions of the autonomic nervous system are the somatic nervous system and the enteric nervous system.

• The two divisions of the autonomic nervous system are the sensory nervous system and the motor nervous system.

The role of the parasympathetic division in the autonomic nervous system is to:

• increase heart rate and energy expenditure

• decrease heart rate and promote digestion

• stimulate the fight or flight response

• regulate voluntary muscle movements

The cells in the nervous system that carry information are called ______.

• Neurons

• Axons

• Dendrites

• Glial cells

The insulation around the neuron is called ______, which functions similarly to the plastic coating of an electrical wire.

• Myelin

• Axon

• Dendrite

• Synapse
