Exam 4 Anatomy

Front

Which neuroglia cell type secretes CSF?

Back

Ependymal cells are responsible for the secretion of cerebrospinal fluid (CSF).

Front

What is the role of the sympathetic system during exercise?

Back

The sympathetic system must vasodilate the airways to achieve more airflow into and out of the lungs during exercise.

Front

What does 'fight or flight' refer to?

Back

'Fight or flight' refers to an increase in activity of the sympathetic system, preparing the body for stressful situations.

Front

What does 'rest and digest' refer to?

Back

'Rest and digest' refers to an increased activity of the parasympathetic system, promoting relaxation and digestion.

Front

Where is the neuronal cell body for a preganglionic sympathetic neuron located?

Back

The neuronal cell body for a preganglionic sympathetic neuron is located at levels T1 through L2 of the spinal cord.

Front

What is the function of astrocytes in the nervous system?

Back

Astrocytes support neurons, maintain the blood-brain barrier, and regulate blood flow in the brain.

Front

What is the role of microglia?

Back

Microglia act as the immune cells of the central nervous system, responding to injury and disease.

Front

What is the function of oligodendrocytes?

Back

Oligodendrocytes provide support and insulation to axons in the central nervous system by forming myelin sheaths.

Front

What is the difference between the sympathetic and parasympathetic systems?

Back

The sympathetic system prepares the body for 'fight or flight' responses, while the parasympathetic system promotes 'rest and digest' functions.

Front

What is the significance of the sympathetic chain ganglia?

Back

The sympathetic chain ganglia are clusters of nerve cell bodies that are part of the sympathetic nervous system, facilitating communication between the spinal cord and target organs.
