set of glands that regulate activities of certain organs by releasing their chemical products into the bloodstream or lymph system
What is the endocrine system
200
The Brain and the spinal cord. Information comes up the _____ to the ______
What is the Central Nervous System
200
Information sent through the axon in the form of a brief electrochemical impulse. Starts as electrical impulse by ions in the fluid inside and outside the axon.
What is a nerve impulse
200
chemicals that carry information across the synaptic gap from one neuron to the next
Common ones:
Acetlecholine
GABA
Norepinephrine
Dopamine
Serotonin
Endorphins
Oxytocin
What are neurotransmitters
200
Lowest part of the brain. Includes:
Medulla:...
Cerebellum:...
Pons:...
Reticular Formation:...
What is The Hindbrain
200
The Master gland. Hormones released influence other endocrine glands
What is the pituitary gland
300
The network of nerves that connect the brain and spinal cord to other parts. All parts of the nervous system other than the brain and spinal cord.
Divided into the Somatic (nerves linking the spinal cord to the body and sense organs) and the Autonomic (carries information to and from internal organs and glands)
What is the Peripheral Nervous System
300
Electrically charged chemicals in the body. Important ones include Sodium (Na+) Potassium (K+) Chloride (Cl-) and Protein Molecules (A+)
What are Ions
300
Drug that mimics or increases the release of a neurotransmitter.
Cocaine, amphetamines and morphine
What is an agonist
300
Area in which many nerve fiber systems ascend and descend to connect the higher and lower parts of the brain. Responsible for sending information between the brain, eyes and ears
What is the Midbrain
300
Endocrine gland that helps regulate the rate of metabolism
What is the thyroid gland
400
the system that arouses the body.
Blood to brain increases
Pupils dilate
Breathing and heart rate increase
Perspiration increase
Digestion decreases
Stress hormones released
Parasympathetic system calms the body- does opposite.
What is the sympathetic nervous system
400
electrical charge of a neuron at rest, a stable negative charge of an inactive neuron. At this time all electrical forces are balanced
What is Resting Potential
400
a drug that blocks the effect of neurotransmitters
Valium
Treatments for schizophrenia
What is an antagonist
400
Highest level of the brain. Includes:
Thalamus:...
Hypothalamus:...
Limbic System:... (Which includes)
Amygdala:...
Hippocampus:...
What is the Forebrain
400
Gland in the brain that helps regulate body rhythms and sleep cycles
What is pineal gland
500
The body's electrochemical communication circuitry made of BILLIONS of neurons
What is the nervous system
500
Nerve impulse occurred when a neuron sends information down the axon. A brief wave of electrical discharge sweeps in an explosion of electricity that is created by the depolarizing current.
What is Action Potential
500
Once an electrical impulse reaches the threshold, it fires all the way down the axon w/o losing intensity.
What is the All-or-nothing principle
500
Thick band of axons that connect the brain cells in one hemisphere to those in the other
What is the corpus callosum
500
the gland that helps regulate energy levels and the ability to cope with stress
