Exam 14: A: Central Nervous System

Damage to Broca's area of the brain causes a person to become unable to articulate words but still able to make vocal sounds.

The spinal cord extends from the foramen magnum to the fifth lumbar vertebra.

The tertiary sensory neurons are entirely in the cerebrum.

Most axons release neurotransmitters; however,some axons in the hypothalamus release hormones.

The diencephalon consists of the thalamus and the hypothalamus.

One of the major functions of the thalamus is its influence on the activity of the endocrine system.

Formation of the cerebrospinal fluid occurs mainly in the choroid plexus.

The dura mater is the periosteum of the cranial bones,and the pia mater attaches the brain tissue.

The fact that one part of the cerebrum can take on a new function in response to damage to another part of the cerebrum is an example of cerebral plasticity.

The parieto-occipital fissure divides the cerebrum into two hemispheres.

From superior to inferior,the brainstem is composed of the pons,midbrain,and medulla oblongata.

Pyramidal pathways are more often associated with smiles and frowns than are the extrapyramidal pathways.

All spinal reflexes contain interneurons.

Cerebrospinal fluid is absorbed into the venous blood via the choroid plexus.

A physician can use lumbar puncture to withdraw cerebrospinal fluid from the subarachnoid space in the lumbar region of the spinal cord.

The secondary motor area is found in the gyrus just posterior to the primary motor area.

The vomiting reflex is mediated by the cerebellum.

The group of nerve roots that extend below the spinal cord are called the filum terminale.

The diencephalon is part of the brain located between the cerebrum and the top of the brainstem.

Repetition of nerve impulses on the same neuron circuitry produces memory.
