Voltage level where action potential is triggered
what is threshold potential
Change in resting potential either more positive (depolarization) or more negative (hyperpolarization)
What is graded potential
exaggeration of the difference between the 2 ends or 2sides of something
What is hyperpolarization
rapid sequence of depolarization followed by repolarization
What is action potential
Charged membrane/polarized membrane due to NA+/K+ATPase pump and non gated channel activities
What is resting potential
What is Pia Mater
3 layers of Meninges from outer to inner
What is Dura Mater, Arachnoid Mater, and Pia Mater
One neuron receives input from several neurons
what is convergence
2 ends or sides of something are not different or less different than before
ex: battery running low or battery dead
What is depolarization
One neuron sends impulses to several neurons via branching its axon
What is divergence
Neurotransmitters can be these 3
What are monoamines
amino acids
peptides
Thalamus, hypothalamus, pineal gland, posterior pituitary gland
what is the diencephalon
This connects the 3rd ventricle to the lateral ventricles
What is the interventricular Foramina
Ridges or convolutions
Shallow grooves in surface
Connects cerebral hemispheres
What are
Gyri
Sulci
Corpus Callosum

1. Parietal Lobe
2. Occipital Lobe
3. Temporal Lobe
4. Frontal Lobe
5. Insular Lobe
Major center for proprioception
Connected to spinal cord has midbrain, pons, medulla, oblongata
what is cerebellum
what is brainstem
Brain and spinal cord has this type of organization
Somatotopic Organization
This lies under the cerebral cortex. Contains bundles of myelinated axons that connect neuron cell bodies in cerebral cortex to other portions of nervous system
What is white matter of cerebrum
Cerebral Cortex
Thin layer of ______ ______ which make sup outer most layer of all outer lobes of the cerebrum
What is gray matter
Receives all sensory impulses (except sense of smell)
Maintains homeostasis by regulating visceral activities
What is the thalamus
what is the hypothalamus
Controls emotional responses, feelings, behavior oriented toward survival
what is Limbic System
Brainstem connects brain to spinal cord and consists of 3 things top to bottom
what is midbrain (top), Pons (middle), Medulla Oblongata (bottom)
Short section of brainstem, lies between diencephalon and pons
what is the midbrain
