Term
What is a neuron?
Definition
A neuron is a cell within the nervous system which has the capability of transmitting information to other neurons.
Term
What are nerve impulses?
Definition
Nerve impulses are electro-chemical signals that transmit from one neuron to another.
Term
What is the Synapse?
Definition
The synapse is the site where transmission of a nerve impulse from one neuron to another occurs. It includes the synaptic knob, the synaptic gap, and the reptor site of the receiving neuron.
Term
What is a synaptic gap?
Definition
A synaptic gap is a small gap between neurons.
Term
Excitatory influences occur when...
Definition
Excitatory influences occur when transmission of a nerve impulse increases the likelihood that the receiving neuron will generate its own nerve impulse.
Term
Inhibitory influences occur when...
Definition
Inhibitory influences occur when transmission of a nerve impulse decreases the likelihood that the receiving neuron will generate its own nerve impulse.
Term
Central Nervous System(CNS) consists of the two following:
Definition
the CNS contains the brain, and spinal cord.
Term
The Peripheral Nervous System (PNS) transmitts signals between...
Definition
The (PNS) transmitts signals between the CNS and the muscles, glands, organs, and sense receptors of the body
Term
What is a Nerve?
Definition
A nerve is a bundle of axons in the peripheral nervous system.
Term
Motor Nerves send...
Definition
Motor nerves send signals from the CNS to the muscles, glands, and organs.
Term
Sensory nerves send...
Definition
sensory nerves send signals from the CNS to the muscles, glands and organs.
Term
what is the spinal reflex?
Definition
The spinal reflex is when a response is produced by transfer of the signals from sensory nerves to motor nerves within the spinal cord.
Term
What are the three things in the CNS does age change?
Definition
Age changes the # of neurons, cell size, the # of synapses, and myelinization
Term
The brain stem contains the...
Definition
The brain stem contains the pons and the medulla
Term
The cerebellum:
Definition
the cerebellum controls  motor movements and helps them flow smoothly.
Term
The hypothalamus regulates which system in our bodies?
Definition
The hypothalamus regulates the endocrine system (controls the reproductive system and hormones)
Term
The limbic system regulates:
Definition
The limbic system regulates the basic survival-related motives and emotions
Term
The limbic center also controls this center:
Definition
the pleasure center
Term
The hippocampus is known as:
Definition
The hippicampus is AKA the "Gateway to Memory"
Term
H.M. was the man known for being unable to:
Definition
H.M. was unable to form concious new memories- he could only remember past memories from before the surgery.
Term

Definition
Term
The cerebral cortex is the:
Definition
Division between the left and right side of the brain.
Term
The somatosensory cortex is...
Definition
The area on the brain matter (on the outermost layer) that controls the different concious parts of the body like the arms, legs, hangs, fingers, toes, etc.
Term
Apraxia is...
Definition
A disorder that interferes with natural motor planning and execution. It makes simple tasks like grabbing a pencil difficult. The hand will fumble around the pen, and then shake if it is able to grasp onto it.
Term
Agnosia is...
Definition
Agnosia is the disorder that messes with visual recognition. The patient will often be unable to label what he/she sees but she/he can still describe it without knowing what it is called.
Term
Aphasia is:
Definition
Aphasia is the disorder of language ability. It causes the patient to slur words, and jumble up the sentences so that they are not able to be understood.
Term
Expressive is AKA
Definition
expressive is brocas area
Term
Receptive is AKA
Definition
receptive is Wernicke's area
Term
The Frontal lobes control...
Definition
Planning and Personality. Etc: the curious case of Phineas Gage- when he was working on the railroads a pole went through his frontal lobes and inhibited him to control his personal thoughts and caused him to act spontaneous and rude.
Term
Hemispheric Specialization describes:
Definition
Hemispheric specialization describes the different actions of the different sides of the brain.
Term
The left brain controls:
Definition
The left brain controls verbal skills, and sequential analysis
Term
The right brain controls...
Definition
The right side of the brain controls the visual and spatial pattern analysis
Term
Concious awareness for split brain patients:
Definition
Split brain patient's brains are very unique, the left and right sides of the brain can work independently and then they put the information together for the patient to understand. Often the left side of the brain creates reason for the right side of the brain's actions.
