Q

How do the nervous system and the endocrine system differ?

A

The endocrine system slowly releases hormones into the bloodstream, he nervous system is designed to act instantaneously by transmitting electrical impulses to specific body locations

Q

Name functions of the nervous system

A

The nervous system:
* coordinates** voluntary **(conscious) activities, such as walking, talking, and eating
* controls involuntary (unconscious) functions, such as reflexes to pain, body changes related to stress, and processes related to thoughts and emotions.

Q

What is the main function of the PNS
peripheral nervous system?

A

Q
  • form a supporting network by twining around nerve cells or lining certain structures in the brain and the spinal cord
  • Others bind nervous tissues to supporting structures and attach the neurons to their blood vessels.
  • Certain small glial cells are phagocytic that protect the CNS from disease by engulfing the invading microbes, destroying them, and clearing away debris
  • Neuroglia are of clinical interest because they are a common source of tumors (gliomas) of the nervous system.
A

neuroglial, or glial cells

Q

cerebrum
cerebr/o

A

largest part of the brain containing the cerebral cortex, as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system. The cerebrum develops prenatally from the forebrain.
