Module 2 Flashcards
Neurons are:
nerve cells that make up the Nervous system
Electrical impulses are:
what neurons carry
Dentries:
the extension that carries electrical impulses through the cell body
Axons;
the extension that releases the electrical impulses
Nerves are:
Axons that are going to the same place in the body so they bunch up
Motor neurons;
Carry impulses away from the brain and spinal cord to cause a reaction
Sensory neurons:
Carry impulses toward the brain and spinal cord.
A stimulus is a:
detectable change in what is going on around you,Sensory receptor.
a Sensory receptor
react to stimulus
association neurons:
are what act between sensory neurons’ axons and motor neurons’ dendrites (AKA interneurons)`
Reflex
is a result of a stimulus process
Mixed Nerves :
carry both sensory and motor neurons in their nerves
the peripheral nervous system is made up of :
Motor, sensory, and mixed nerves
the central nervous system is made up of :
association neurons, brain and the spinal cord
the Cerebrum is where the
thinking happens
the cerebellum refines;
muscle movement and balance
the Brain stem controls
vital functions (breathing, heart rate, blood pressure, swallowing , sleeping and waking.
a synapse is:
the space between an axon of one neuron and a dendrite of another
neurotransmitters are
what are released by the sending neuron’s axon and bound to the receiving neuron’s dendrites
Glutamate is
a neurotransmitter that is usually used in the brain it often firs off an impulse
GABA is
(gamma aminobutyric acid) a neurotransmitter that can inhibit a transmission. (AKA ignore a sound)`
Acetylcholine is
a neurotransmitter that has quieting effects in some parts of the brain and waking in others. it promotes restful sleep, memory and keeps you from being depressed.
A high is a:
a temporary felling of intense pleasure and energy (which is brought on by dopine flooding)
An addict is when
someone becomes physically or emotionally dependent on a drug
A concussion is the result of
a knock on the head or a bruise on the head
a seizure is
an abnormal excessive activity of the brain’s neurons often with no clear reason
an epilepsy is
diagnosed when someone has multiply seizures
meningitis is
inflammation in the protective layers of the brain (AKA meninges)
encephalitis is
inflammation of the brain itself
An ischemic stroke is when
there is loss of blood in the brain resulting in neuron death
edema is when
something is swelling
aneurysm is when
a weakened area of a blood vessel that breaks
A hemorrhagic stroke is when
a brain blood vessel breaks and pools in areas of the brain
A hematoma is a
blood cot that is below the surface
the endocrine system is made up of
glands and hormones
glands produce
hormones and release them into the blood stream
a target cell
is a cell with a receptor for a hormone
a receptor is
what tells the hormone where to go
the pineal body produces
hormones that enhance or discourage sleep
serotonin promotes
wakefulness
melatonin encourages
sleep
the pituitary gland and
the hypothalamus control growth and send out signal hormones to other endocrine glands
adrenal glands produces
a short - term hormone that produces a quickly prepares the body for conflict
Cortisol
is a hormone that is produced in the pituitary gland that reduces inflammation
Epinephrine
is a hormone that speeds up the heart
the thyroid produces
a hormone called thyroxine that raises the metabolic rate of cells
the pancreas produces
insulin that lowers glucose levels in blood
reactive hypoglycemia is when
the insulin over reacts sometimes as a result of sugary snacks on an empty stomach
diabetes is
a disease of constantly high blood levels .
type 1 diabetes is
when there is a lack of insulin production by the cells in the pancreas
type two is when
glands don’t respond normally to the insulin
insulin resistant is
when the cells of the body no longer accept the insulin that Is available
female reproductive
estrogen and progesterone
male reproductive:
testosterone
list 5 signs of inflammation
1 pain 2 swelling (edema) 3 redness 4 temperature increase of the inflamed tissues 5 hypersensitivity
