Brain
the largest part of the brain; has two hemispheres and 4 lobes
Cerebrum
regulates rate and depth of breathing
pons
Function of the nervous system described as
Detecting stimuli, such as pressure, temperature changes, taste,smell, or light and send a message in the form of impulses to the brain and spinal cord
sensation
Short, branchlike extensions which conduct electrical impulses toward the cell body
Dendrites
the cartilage funnel that directs sound waves into your ear
Auricle or Pinna
The inner most layer in the eye that contain the photoreceptors is the
retina
a condition which, real or imagined, are difficult to control
anxiety
interprets the sense of sight
occipital lobe
functions to coordinate the muscular movements and helps the muscles move gracefully and efficiently. Also helps body with balance. ; 2nd largest part of the brain ("little cerebrum")
Cerebellum
function of the nervous system described as
The nervous system receives and interprets sensory stimuli from the body and determines an appropriate response to those stimuli.
Integration
contains the genetic information of a neuron
nucleus
first structure of the middle ear, vibrates with sound waves and passes vibrations to middle ear bones
tympanic membrane (ear drum)
the 'white' of the eye is called
sclera
blood vessel breaks open and blood leaks into the brain
hemorrhagic stroke
responsible for our ability to learn, think, move, problem solve, concentrate, etc.
Frontal lobe
located bellow the cerebellum and connectes the spinal cord to the brain. composed of three structures
brain stem
Function of the nervous system described by
The brain sends impulses through motor nerves to muscles and glands to cause movement or secretion of hormones
Movement
extends from cell body; carries nerve impulses to other neurons
axon
Where are the ossicles found in the ear
middle ear
structure responsible for pupil diameter and eye color
iris
an infection that causes inflammation of the brain and spinal cord coverings; most commonly bacterial or viral
meningitis
interprets the sense of balance and hearing; contains the hippocampus
temporal lobe
small section of the brainstem superior to the pons. It serves as a relay station for both sensory and motor nerve impulses and contains reflex centers for hearing, vision, and posture
midbrain
Three layers of the meninges
Dura mater, Arachnoid mater and Pia Mater
contains the nucleus and other cellular organelles
cell body
This part of the ear helps to equalize pressure inside the ear
eustachian tube
clear window in front of the eye allowing for light waves to enter the eye
cornea
brain disorder involving repeated seizures of any kind, caused by abnormally excited electrical impulses in the brain
epilepsy
Interprets many of our senses: pain, touch, temperature, and taste
parietal lobe
continuous with the spinal cord and helps to regulate the heartbeat, blood pressure, breathing, swallowing, hiccupping, and vomiting. It also relays nerve impulses between the brain and the spinal cord
major communication link between the brain and the rest of the body.
It can process many reflexes – unconscious, automatic responses to stimuli.
with the brain it makes up the central nervous system
spinal cord
the insulating membrane that wraps the axon with fat. Strengthening neuron connection
myelin sheath
what is another name for middle ear infection?
otitis media
Farsightedness and nearsightness are also known as
myopia and hyperopia
Post traumatic impairment of neural function caused by a direct blow to the head resulting in bruising of the brain. Should be treated with removal from play, rest and avoiding re-injury
concussion
meninges
small bulge above the medulla oblongata. It is important to help us regulate the rate and depth of breathing.
pons
how many pairs of spinal nerves branch from the spinal cord?
- Controlling things such processes as breathing, arm movement and leg movement.
31
Neurons that detect changes and carry impulses away from the brain and spinal cord to muscles
motor neurons
snail shaped, fluid filled structure that continues the vibrations
cochlea
mucus membrane of the eyelid is known as
conjuctiva
also known as a CVA or cerebrovascular accident, occurs when there is an interruption of the blood supply to any part of the brain. - two types
Stroke - ischemic and hemmorhagic
clear, watery fluid which bathes the brain and spinal cord for protection by acting as a shock absorber, and allows for the exchange of nutrients and waste products between the blood and the nervous tissue
Cerebrospinal Fluid
brain is composed of three main parts:
identifies the sense of smell and taste;
identifies the sense of hearing and touch;
identifies the sense of vision
chemoreceptors
mechanoreceptors
photoreceptors
type of neurons that detect senses and carry impulses to the brain
sensory
fluid filled canals attached to inner ear in charge of balance and 'levelness'
semicircular canals
normal 'loss of accommodation' power of the eye that results as a consequence of aging
presbyopia
A mental disorder in which a person loses contact with reality
schizophrenia
