Nervous System Structures (Reversed) Flashcards
Connects the brain and body. Also controls reflexes independently of the brain.
Describe the spinal cord
Embryros contain a forebrain, midbrain, and hindbrain that differentiate into the major brain parts.
Describe the brain in embryos
mid brain
The brain stem is also called what?
homeostasis, movement and conduction of information
What does the brain stem control
Medulla oblongata ,Pons, reticular formation
The brain stem is has what three parts?
Transfers info from the PNS to the brain.
What does the Pons do?
coordinates large scale movements (running)per instruction from the upper regions and controls autonomic functions
What does the Medulla oblongata
a network of neurons that filters information before it gets to the brain
What is the reticular formation
whether or not you pay attention to incoming data
What does the reticular formation determine?
Sleep
____ is also controlled by the brain stem which is believed to help process learning and memory.
hindbrain
Cerebellum is also called what?
controls movements and balance. Helps learn motor skills
What does the cerebellum do?
cerebrum; hand eye coordination
The cerebellum checks motor commands from the _______. This is helps with what?
hearing; visual
The cerebellum receives _______ and _____ input.
forebrain
The diencephalon is also called what?
pineal gland
The epithalamus is also called what?
epithalamus, thalamus, and hypothalamus
The diencephalon contains what parts?
stores all information from the senses before sending them the cerebrum
What does the thalamus do?
rhythms (sleep)
What does the epithalamus control?
body temp
What does the hypothalamus control?
main center of information processing
Describe the cerebrum
outer layer of gray matter
What is the cerebral cortex
pain, pressure, temp, muscles
What do somatosensory organs control?
cerebral cortex
The _______ _____ receives information from the somatosensory.
hemispheres
The left and right __________ each controls the opposite side of the body.
corpus callosum
The hemispheres are connected by an axon known as what?
Lateralization
The differences in the left and right is known as what?
math and logic
The left hemisphere is better at what?
better at recognition, patterns, and nonverbal thinking (creativity)
The right hemisphere is better at what?
Frontal lobe, Occipital lobe, Temporal lobe, Parietal lobe
The Cerebral Cortex is separated into four lobes. What are they?
Neural plasticity
What ability of the brain to change is called what?
Synapses; memories
_________ can be strengthened or weakened by frequency of use which leads to ________.
mechanoreceptors
The sense receptors that control pressure, touch, sound is called what?
chemoreceptors
The sense receptors that control taste, smell, solute concentration is called what?
electromagnetic receptors
The sense receptors that control light, electricity, magnetism concentration is called what?
thermoreceptors
The sense receptors that detect hot and cold is called what?
pain receptors
The sense receptors that detect harmful conditions and solicits a reaction to minimize damage
tympanic membrane; stapes
Sound waves travel in the ear and vibrates the ______ ______ which vibrates a bone called a ______.
cochlear duct
The stapes causes fluid in the _______ _____ to vibrate thus moving hairs in there.
auditory nerves
The hairs sends signals to ________ ______.
semicircular canal
Fluid in ____________ ____ move hairs in response to gravity or out head tilting for equilibrium
when a receptor protein binds to a molecule and begin a transduction pathway that stimulates a taste nerve
How the taste occurs?
is all nerve cells that bind to a molecule and sends signals directly to the brain. (linning of the nose, mucus needed). causes smell
What is the olfactory
cornea
Light comes in the ______.
iris; pupil
The ___ can dilate the _____ to control the amount of light that hits the flexible lens of your eye.
photoreceptors; cones; rods
The retina contains __________ that detect color in ______. and black and white in ____.
optic nerve
The _____ ______ carries visual input to the brain.
