Categorize the following: intestinal muscles, heart muscles, hand muscles, and neck muscles.

Intestinal and neck muscles are skeletal muscles; heart and hand muscles are smooth muscles.

Heart and neck muscles are long and slender; hand and intestinal muscles are spindle shaped.

Intestinal and heart muscles are involuntary muscles; hand and neck muscles are voluntary muscles.

Heart and intestinal muscles allow for big movements; hand and neck muscles allow for smooth movements.

What initially causes a nerve impulse?

release of enzymes out of the neuron

Which best compares and contrasts red blood cells and white blood cells?

Both are produced in the red bone marrow. Red blood cells transport oxygen, and white blood cells protect the body against disease.

Both are produced in the red bone marrow. Red blood cells carry all blood components, and white blood cells help the body heal cuts.

Both are made of hemoglobin. Red blood cells transport oxygen, and white blood cells protect the body against disease.

Both are made of hemoglobin. Red blood cells carry all blood components, and white blood cells help the body heal cuts.

appendicular skeleton

Which part of the neuron below is indicated by the arrow, and what is its function?

The axon carries information through electrical impulses away from the cell body to the axon terminals.

The axon contains the nucleus that controls all the activities of the cell.

The dendrites regulate the substances that go in and out of the cell.

The dendrites carry the electrical impulses from the signal receivers to the cell body.

Which of the following actions involves voluntary muscle movement?

movement of food through the digestive tract
