Describe the two parts of the nervous system and what each one entails.
Central nervous system: brain and spinal cord - governing center.
Peripheral nervous system: 12 pairs of cranial nerves, 31 pairs of spinal nerves, and all the
branches
-Is afferent, meaning it carries sensory messages to the CNS from sensory receptors, and motor
(efferent) messages from the CNS to muscles and glands.
Describe the Brainstem
central core of the brain, consists of three areas
-Midbrain
-Pons
-Medulla
Describe the Midbrain
anterior part of the brain stem that has the basic tubular structure of the spinal cord
merges into the thalamus and hypothalamus and contains motor neurons and tracts.
Describe the Pons
,enlarged area containing ascending and descending fibre tracts
assists with respiratory rhythm.
Describe the Medulla
continuation of the spinal cord of the brain that contains all ascending and descending fibre tracts
vital autonomic centres, as well as nuclei for some of the cranial nerves
Describe the diencephalon
composed of the hypothalamus and thalamus
Describe the hypothalamus
major control centre with many vital functions, such as controlling temperature, heart rate, blood
pressure, regulating sleep, etc.
Describe the thalamus
main relay station for the nervous system.
Describe the cerebral cortex
outer layer of nerve cell bodies, looks like "gray matter" because it lacks myelin (that conducts
impulses faster, is called white matter)
It is the centre for human's highest functioning, and is divided into two hemispheres.
Each hemisphere is divided into four lobes.
, Describe the frontal lobe
areas concerned with personality, behaviour, emotion, etc.
Describe the precentral gyrus
voluntary movement
Describe the parietal lobe
primary center for sensation
Describe the occipital lobe
primary visual receptor center
Describe the temporal lobe
primary auditory centre for sensation
Describe the wernicke's area
language comprehension
If damaged, results in receptive aphasia.
Describe the broca's area
mediates motor speech.
If damaged, expressive aphasia results, and the person cannot talk, but is able to understand
language
