Flashcards in General Organization Of The Nervous System Deck (37)
What does the nervous system consist of?
Peripheral NS and Central NS
The Peripheral Nervous System consist of:
Cranial nerves and spinal nerves
The Central NS consist of :
Brain and spinal cord
Which is the largest portion of the brain?
What does the cerebrum consist of?
2 Cerebral hemispheres (right and left hemispheres)
What is the right hemisphere responsible for?
Art, music, imagination, involved in left side sense and motor.
What is the left hemispheres responsible for?
Language, logic, math, involved in right side sense and motor.
What is corpus callosum ?
Thick white band of axons connecting right and left hemispheres.
In cerebrum there is white matter covered with layer of neural cortex(grey). True or false?
Name the 5 cerebral lobes each Cerebral hemisphere consist of.
Frontal lobe responsible for:
Judgement, personality, motivation, voluntary motor, Broca's area on left side.
Parietal lobe is for:
Temporal lobe is for:
Auditory areas, learning, memory, speech understanding.
Occipital lobe is for:
Which lobe is not visible and lies deep to lateral fissure?
The Cerebral hemispheres have functional regions which are?
Motor, sensory and association areas
Functions of the cerebrum. Hint:
Controls your thinking, speech,movement and identifies the information gathered by your sense organs.
Do Cerebral hemispheres have some functional differences. True/false
Cerebral hemispheres have do not have anatomical resemblance- lateralization of cortical functioning. True/ False
False, they do have anatomical resemblance
The brain consists of four ventricles name them and what are they filled with?
1. 3rd ventricle
2. 4th ventricle
3. Two lateral ventricle - central and inferior
They are filled with CSF
Cerebral cortex is the outer portion of cerebrum and is composed of:
Grey matter(bundles of neuron cell bodies) and bulk of cerebrum is white matter (bundles of myelinated nerve fibers/axons)
The thalamus is the major______and important in_______control. It serves as a_______center for preliminary processing of all______input on it's way to the _____.
Sensory Relay station, motor ,synaptic integrating, sensory ,cortex
Give the functions of the hypothalamus. Hint: 5C's, 2P's, S
1. Controls body temperature
2. Controls thirst and urine output
3. Controls food intake
4. Controls anterior pituitary hormone secretion
5. Controls uterine contractions and milk ejection
6. Produces posterior pituitary hormones
7. Plays a role in emotional and behavioral patterns
8. Serves as a major autonomic nervous system coordinating center, which in turn affects all smooth muscle, cardiac muscle, and exocrine glands.
The brain stem connects the brain to the______.
The nerves in the brain stem control your ______,_______, and _______.
Heart rate, breathing and blood pressure
The tectum is the corpora quadrigemina with two pairs sensory nuclei, which are?
1. Superior colliculi
2. Inferior colliculi
What is the function of superior colliculi?
Is a relay station for visual information
What is the function for inferior colliculi?
Is a relay station for auditory information
Describe what is tegmentum?
Is a red nucleus(many blood vessels) and is substantia nigra( pigmented gray matter) it regulates motor output.
