List the 5 types of human spinal nerves.
| | | | | | |
Humans have 1-eight pairs of cervical (cranial) nerves, 2-
| | | | | | | |
twelve pairs of thoracic nerves, 3-five pairs of lumbar nerves,
| | | | | | | | | |
4- five pairs of sacral nerves, and 5-one pair of coccygeal
| | | | | | | | | | |
nerves
|
What is the most important nerve of the cervical plexus and what
| | | | | | | | | | |
structure does it supply?
| | | |
The phrenic nerve is the most important nerve of the cervical
| | | | | | | | | |
plexus and supplies both motor and sensory fibers to the
| | | | | | | | | |
diaphragm.
|
List the five final nerves that come from the Brachial plexus.
| | | | | | | | | |
,Axillary nerve, the radial nerve, the median nerve, the
| | | | | | | |
musculocutaneous nerve and the ulnar nerve.
| | | | | |
Describe the detail the structure of spinal nerves within the
| | | | | | | | |
vertebral column.
| |
Each spinal nerve emerges from the spinal cord by two short
| | | | | | | | | |
roots, the dorsal root which contains the axons of afferent
| | | | | | | | | |
sensory neurons, which conduct impulses to the cord and the
| | | | | | | | | |
ventral root which contains the axons of efferent motor
| | | | | | | | |
neurons, which conduct impulses away from the cord. These
| | | | | | | | |
two roots join just before a spinal nerve leaves the vertebral
| | | | | | | | | | |
column.
|
How is the hypothalamus involved with the entire internal
| | | | | | | |
environment of the body and the endocrine system in
| | | | | | | | |
particular?
|
The hypothalamus maintains homeostasis, the constancy of
| | | | | |
the internal environment and controls the pituitary gland and
| | | | | | | | |
serving as a link between the nervous and endocrine systems
| | | | | | | | | |
, All except what sensory impulses are channeled through the
| | | | | | | |
thalamus?
|
All sensory impulses (except those associated with the sense of
| | | | | | | | |
smell) are channeled through the thalamus.
| | | | | |
Describe the parietal lobe of the cerebrum.
| | | | | |
The parietal lobe receives sensory information from receptors
| | | | | | |
in the mouth for taste and located in the skin, such as those
| | | | | | | | | | | | |
for touch, pressure, and pain.
| | | | |
Describe the temporal lobe of the cerebrum.
| | | | | |
The temporal lobe has sensory areas for hearing and smelling.
| | | | | | | | |
Describe the occipital lobe | | |
The occipital lobe interprets visual input.
| | | | |
Describe the detail the structure of spinal nerves after leaving
| | | | | | | | |
the vertebral column.
