The nervous system is divided into two different systems, what are they? | the Central Nervous System (CNS) and Peripheral Nervous System (PNS). |
The CNS is comprised of what? | The brain and spinal cord. |
The PNS is comprised of what? | The spinal and cranial nerves. |
Afferent pathways (ascending pathways) carry sensory impulses which way? | They carry sensory impulses toward the CNS. |
Efferent pathways (descending pathways) carry impulses which way? | They carry sensory impulses away from the CNS to effector organs, such as muscles, (smooth or skeletal) and glands. |
The voluntary (somatic) nervous system is composed of: | nervous system fibers that connect the structures of the CNS with skeletal muscles and integument. |
The involuntary (autonomic) nervous system is divided into the: | Sympathetic and parasympathetic branches. |
Sympathetic nervous system... | Fight or flight |
Parasympathetic nervous system... | Rest and relax |
What is the largest component of the CNS? | The brain. |
The entire CNS is enclosed by a set of three membranes collectively known as: | The meninges. |
The cranial meninges consist of three layers: | The dura mater, the arachnoid mater and pia mater. |
The dura mater is the: | External thick, dense fibrous membrane. |
The arachnoid mater is the: | Intermediate, delicate membrane. |
The pia mater is the: | Internal delicate, vascular membrane. |
The subarachnoid space between the arachnoid and pia is actually a space that contains? | CSF, trabeculae, arteries, and veins. |
The lateral ventricles are important for what? | ICP monitoring, CSF drainage, or placement of a CSF shunt. |
CSF has what role? | It surrounds the brain and spinal cord, it provides a protective mechanism by acting as a shock absorber, and participates removal of waste from the cerebral tissue. |
CSF is made up of how many ml? | About 125-150 ml of CFS. |
Neurotransmitters for the sympathetic nervous system are? | Acetylcholine, epinephrine, and norepinephrine. |
There are four lobes in the brain, what are they? | Frontal, parietal, temporal and occipital. |
Frontal lobe functions are what? | Personality, behavior, intellect, short term memory, motor speech. |
Parietal lobe functions are what? | Sensory integration, object recognition, localizes sensory information to the body surface. |
Temporal lobe functions are what? | Emotion, long term memory, processing of auditory input, sensory speech. |
Occipital lobe functions are what? | Processing of visual input. |
