Question 1

What are the three principal regions of a neuron? Which part contains the nucleus?

Answer 1

Cell body, dendrites, and an axon. The cell body contains the nucleus.

Question 2

Where are macromolecules?

Answer 2

A very large type of molecule, like proteins, often composed of thousands of atoms or more.

Question 3

Where in the neuron are macromolecules produced?

Answer 3

The nucleus, located in the cell body. It is the nutritional center of neuron.

Question 4

What are the two subcategories of the nervous system?

Answer 4

Central nervous system (CNS): Including the brain and spinal cord.

Peripheral nervous system (PNS): Includes the cranial nerves arising from the brain and the spinal nerves arising from the spinal cord.

Question 5

What is the difference between the CNS and PNS?

Answer 5

The peripheral nervous system or PNS contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. The peripheral nervous system’s main job is to send information gathered by the body’s sensory receptors to the CNS as quickly as possible.

Question 6

What is a cluster of cell bodies in the CNS (central nervous system) called?

Answer 6

Nuclei. NOTE: NOT TO BE CONFUSED WITH PLURAL NUCLEUS

Question 7

What is a cluster of cell bodies in the PNS (peripheral nervous system) called?

Answer 7

Ganglia.

Question 8

Even though the axon of a motor neuron is connected TO the hamstring muscle, where is it’s cell body located?

Answer 8

Back in the CNS. It’s axon extends out into the PNS to the muscle. Some neuron axon lengths can be a meter long.

Question 9

The axons of peripheral neurons that travel a common route are bundled together to form ____?

Answer 9

Nerves

Question 10

What are the three classes of neurons?

Answer 10

Sensory neurons, Motor neuron, and Interneurons.

Question 11

What are sensory neurons?

Answer 11

They pick up information about what’s going on inside and outside of the body, and then bring that back to the CNS. Fingers feeling a hot surface are an example.

Question 12

What are motor neurons?

Answer 12

They get information from other neurons and convey commands to your muscles, organs and glands. For instance, if you picked up a hot coal, motor neurons in the muscles in your fingers would cause your hand to let go.

Question 13

What are interneurons?

Answer 13

They receive information from other neurons (either sensory neurons or interneurons) and transmit information to other neurons (either motor neurons or interneurons).

Question 14

What are the most common type of neuron?

Answer 14

Interneurons

Question 15

How many vaginas do kangaroos have?

Answer 15

3. One in the middle for birthing the, and one on either side of it for sperm delivery. to one of two uteruses.

Question 16

When did Gregor Mendel live?

Answer 16

1822 - 1884,

Question 17

Who is Gregor Mendel?

Answer 17

Gregor Mendel was an Austrian monk who discovered the basic principles of heredity through experiments in his garden (peas). Mendel’s observations became the foundation of modern genetics and the study of heredity, and he is widely considered a pioneer in the field of genetics

Question 18

What is Great Man Theory?

Answer 18

The Great Man theory is a 19th-century idea according to which history can be largely explained by the impact of “great men”, or heroes; highly influential individuals who, due to either their personal charisma, intelligence, wisdom, or political skill used their power in a way that had a decisive historical impact.

Question 19

What is galvanization? How is is typically done?

Answer 19

The process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
