Nervous System Flashcards
Indentations found on the cerebrum of the brain
Sulcus
Functions, such as, breathing and heart rate are controlled by this part of the brain
Medulla Oblongata
This lobe processes information, such as, touch, pressure and pain
Parietal Lobe
This cranial nerve controls neck movement
Cranial Accessory
This structure allows for communication between the left and right hemispheres
Corpus Callosum
This Lobe of the brain interpret sound and language
Temporal Lobe
This part of the brain coordinates movement and motor learning
Cerebellum
This part of the brain relays sensory and movement information from the body to the cerebrum and vice versa.
Thalamus
This part of the brain controls, hunger, thirst and circadian rhythm
Hypothalamus
This part of the brain stimulates breathing and controls sleep
Pons
This part of the brain secretes hormones that can affect organs and glands
Pituitary Glands
This part of the brain controls the flow of messages between the body and brain
Brain Stem
What input is considered the tapping of the knee?
Sensory
When the information goes to the central nervous system what is the purpose of it?
Integration
The response or movement of the knee is considered
Motor output
A neuron contains many fiber-like extensions called
Dendrites
Site if regulation of water balance and body temperature
Hypothalamus
Contains reflex centers involved in regulating respiratory rhythm in conjunction with lower brain Stem centers
Pons
Responsible for the regulation for posture and coordination of skeletal muscle movements
Cerebellum
Important relay station for afferent fibers traveling to the sensory cortex for interpretation
Medulla Oblongata
Large fiber tract connecting the cerebral hemispheres
Corpus Callosum
Shrugging the shoulders
Cranial Accessory
Smelling a flower
Olfactory
Rising the eyelids and focusing the lens of the eye for accommodation; constriction of the eye pupils
Oculamotor
Slows the heart; increases the mobility of the digestive tract
Vagus
Involving in smiling
Facial
Involved in chewing food
Trigeminal
Listening to music, seasickness
Vestibulocochlear
Secretion of saliva; tasting well-seasoned food
Glossopharyngeal/Facial
Involved in “rolling” the eyes
Trochlear, Abducens, Optic
Feeling a toothache
Trigeminal
Reading Tennis magazine or this study guide
Optic
Purely sensory
Olfactory, Optic, vestibulocochlear
Piercing the skin
Stimulus
What tissue is the effector?
Muscle or gland tissue. Skeletal muscle
How many synapses occur in this reflex arc?
2
Releases neurotransmitters
Axon termital
Conducts electrical currents toward the cell body
Dendrites
Increases the speed of impulse transmission
Myelin sheath
Location of the nucleus
Cell body
Generally conducts impulses away from the cell body
Axon
Rounded surfaces
Gyrus
Three parts of the nervous system
- Brain
- Spinal cord
- Neurons
Includes brain and spinal cord
Central Nervous System
Nerves that communicate motor and sensory signals between the CNS and the rest of the body
Peripheral Nervous System
Overlapping Functions:
Sensory input, integration, motor output
The transmitting cell
Presynaptic cell
The target cell
Postsynaptic
A vesicle at the top of presynaptic axon
Synaptic vesicles
Chemical messengers that are contained in synaptic vesicles
Neurotransmitters
Inside of the membrane
Negative charge
Outside of membrane
Positive charge
Causes by the movement of ions across the plasma membrane
Voltage change
Voltage-gated ion channels situated in small gaps between Schwann cells in the axon
Nodes of Ranvier
