Neurons
What is a neuron?
a nerve cell; the basic building block of the nervous system
This is the body's speedy electrochemical communication network, consisting of the CNS and PNS.
Nervous System
A technique that uses magnetic fields and radio waves to produce computer generated images of soft tissue.
MRI- Magnetic Resonance Imaging
The oldest part of the CNS that serves as a crossover point for the nerves.
Brainstem
The Motor Cortex is responsible for:
Controlling voluntary movement//output movement
What function does the nucleus have?
A part of the cell containing DNA and RNA and responsible for growth and reproduction
This is the body's slow chemical communication network with glands and hormones.
Endocrine System
A visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task.
PET- Positron Emission Technology
The Thalamus is the __________ control center that sits on top of the brainstem.
sensory
The Somatosensory Cortex does what?
Registers and processes touch and movement sensations // input
What function do dendrites have?
a neuron's bushy, branching extensions that receive messages and conduct impulses toward the cell body
Glands secrete what substance in order to influence your body?
Hormones
An amplified recording of the waves of electrical activity sweeping across the brains surface.
EEG- Electroenphalogram
Name 2 functions of the cerebrum.
-process sensory input
-coordinates movement output/balance
-enables nonverbal learning and skill memory
-Assists with judgement of time, modulation of emotion, and discrimination between sound and texture.
What is the purpose of the association area(s)?
Not for sensory or motor functions. Involved in higher mental functions.
What function does the terminal ends have?
forms junctions with other cells
The Central Nervous System contains the ____________ and ________ ________.
Brain // Spinal Cord
Several MRI scans being compared side by side can create a (an) __________ scan.
fMRI
What are the 4 lobes of the brain?
Frontal, Temporal, Occipital, Parietal
What is brain plasticity?
The brains ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience.
True of False: The synapse is a gap between neurons that transmits neurotransmitters.
True
The Peripheral Nervous System is composed of the _____________ nervous system and the _____________ nervous system,
Autonomic // Somatic
Allows for the scanning of internal organs to analyze the function of the organs.
SPECT- Single Photon Emission Computerized Tomography
Match the lobe to its function
Frontal, Parietal, Occipital, Temporal
Visual, Auditory, Touch, Humanity, Touch
Frontal- Humanity
Parietal- Touch
Occipital- Visual
Temporal- Auditory
