Exam 14: A: Central Nervous System

Both the pons and medulla oblongata have centers that help regulate respiration.

The interventricular foramen (the foramen of Monro)leads into the fourth ventricle.

Most of the motor tracts of the central nervous system do not decussate.

The filum terminale is the name given to the dura mater below the spinal cord.

The most superficial border of the subarachnoid space is the dura mater.

Cerebrospinal fluid is not found in the epidural space.

"Jet lag" occurs when the biological clock does not match up with the external clock.It is the job of the pineal body to correct this.

The tentorium cerebelli is a sickle-shaped extension of the dura that separates the two hemispheres of the cerebellum.

The meninges are protective coverings,continuous around the brain and spinal cord.

All of the 12 cranial nerves come from one of the three parts of the brainstem.

The cerebellum controls skeletal muscles to maintain balance.

The term used to describe all of the connections within the human cortex to the rest of the brain is connectomes.

The adult brain weighs about 3 pounds.

The deeper,wider groove on the spinal cord can be used to identify the ventral side of the spinal cord.

The epidural space is found only in the area of the spinal cord.

Disruption of cerebrospinal fluid circulation that causes the fluid to accumulate in the epidural space is known as hydrocephalus.

The four large,fluid-filled spaces within the brain are called ventricles.

The cerebrum has more neurons than any other part of the nervous system.

The secondary motor area activates groups of muscles rather than individual muscles.

The vomiting reflex is mediated by the medulla.
