Genetics/Nervous System

Which type of cells provide scaffolding on which the nervous system is built?

• neurons

• glial cells

• axons

• dendrites

Interconnected information processors that are essential for all of the tasks of the nervous system are known as

• glial cells

• cell bodies

• myelin sheath

• neurons

Where is the nucleus of a neuron located?

• cell wall

• soma

• terminal buttons

• neurotransmitters

The chemical messengers of the nervous system are known as

• nodes of Ranvier

• receptors

• neurotransmitters

• terminal buttons

The neurotransmitter, Dopamine, is most know for which effect on the human body?

• decreased pleasure

• increased pleasure

• increased appetite

• decreased anxiety

The central nervous system includes the

• spinal cord and brain

• nerves

• stomach and bowels

• liver and kidneys

Which part of the nervous system is involved in preparing the body for stress-related activities?

• sympathetic nervous system

• parasympathetic nervous system

• homeostasis

• somatic nervous system

When someone has a combination of alleles for a given gene, they are said to be

• heterozygous

• homozygous

• recessive

• dominant

A sudden, permanent change in a gene is known as a

• a range of reaction

• cellular change

• mutation

If a person is bb, they are said to have the

• dominant allele

• recessive allele

• heterozygous gene

• mutative gene
