Neuromuscular: Study Set 3 Flashcards
Is gray matter or white matter composed of nerves without dendrites
white
Is gray matter or white matter composed of capillaries, dendrites, glial cells, and cell bodies
gray
Is gray matter or white matter unmyelinated
gray
Is gray matter or white matter myelinated
white
Do cranial nerves and spinal nerves belong to the CNS or PNS
PNS
Spinal nerves each have an anterior root and a posterior root. What are the roles of each of these nerve roots
the posterior root is afferent meaning it carries sensory information to the CNS to be processed
the anterior root is efferent meaning it carries out motor information away from the CNS
What are the two divisions of the ANS and their definitons
- sympathetic division - prepares the body for emergence response via norepinephrine neurotransmitter
- Parasympathetic division - conserving and restoring energy via acetylcholine neurotransmitter
Which neurotransmitter is responsible for a fight or flight response
norepinephrine
Which neurotransmitter is responsible for calming the body and inhibiting the fight or flight response
acetylcholine
What is the somatic nervous system composed of
peripheral and motor nerve fibers that are all myelinated.
True or False
The five senses are influenced by the ANS
False, SNS
What is the limbic system responsible for
controlling mood and emotions as well as processing and storage of recent memory. Olfaction, control of appetite, and emotional responses to food happen here
What behaviors might arise is there is a lesion in the limbic system
aggression, extreme fearfulness, altered sexual behavior, and changes in motivation
What structure in the brain relays information from ne side of the brain to the other side
corpus callosum
What is the function of the frontal lobe
voluntary movement, speech, judgement, and reasoning. Broca’s area is in the left frontal lobe
Where is Broca’s area located in the brain
left frontal lobe
What is the function of the parietal lobe
sensation of touch, vibration, and temp. Receives sensory information from other parts of the brain. Provides meaning for words and language
What is the function of the temporal lobe
primary auditory and olfaction processing as well as processing other peoples emotions. Wernicke’s area in is the left temporal lobe
Where is Wernicke’s area located in the brain
left temporal lobe
What is the function of the occipital lobe
main center for visual information
Which structure of the brain is responsible for storing and retrieving memories as needed
hippocampus
Which structure of the brain is responsible for voluntary movement, posture, muscle tone, and control of motor responses
basal ganglia
Which structure of the brain is responsible for emotional and social processing as well as fear, pleasure, or arousal.
amygdala
Which structure of the brain is known at the relay center for processing sensory information and executing movement
thalamus
Which structure of the brain receives and integrates information from the ANS and assists in hunger, thirst, regulating hormones/glands, sleep, and body temperature.
Hypothalamus
The tectum and the tegmentum are the two key areas of the midbrain. Which of the two includes superior and inferior colliculi
tectum
The tectum and the tegmentum are the two key areas of the midbrain. Which of the two includes the cerebral aqueduct, periaqueductal gray, reticular formation, substantia nigra, and red nucleus
tegmentum
Which structure of the brain coordinates movement, posture, and balance
Cerebellum
