Nervous System Flashcards
Coordinates the bodily function enabling the person to adapt adapt on the external and internal changes of the environment
Nervous system
What are the two main cells of the nervous system
Neuroglia and neurons
It is the supporting cells in the nervous system
Neuroglia
It is the conducting cells of the nervous system
Neurons
What are the functions of the nervous system
Sensory output integration and motor output
Gathering information to monitor the changes of the internal and external part of the body or the inside in the outside of the body
Sensory input
To process and interpret the sensory input and decide if action is needed
Integration
Are response that integrates the stimuli response activates the muscle or glands
Motor output
What are the structural classification of the nervous system
Central nervous system cns peripheral nervous system pns autonomic nervous system ans
This contains the spinal cord the brain movement spatial awareness cognition creativity personality where we can understand ourselves
Central nervous system
These are nerves outside the brain and spinal cord it talks about the spinal cord which is the c1 to s5 and the cranial nerve
Peripheral nervous system
It is the vital organ of the body it works by schoolmation special awareness creativity and personality
Brain
What are the regions of the brain
Cerebral hemisphere lines of long tristan and cerebellum
It is the largest part of the body contains half the brain mass and the cerebral cortex
Cerebral hemisphere
Is the place where the processing of sensation, perception, voluntary movement, learning, speech and cognition takes place.
Gray matter
Is the place where the processing of sensation, perception, voluntary movement, learning, speech and cognition takes place.
Gray matter
role is to provide communication between different grey matter areas and between grey matter and the rest of your body.
White matter’
What are the surface of cerebral hemisphere are made
They are made of sulci and gyri
Also known as the grooves
S u l c i
Also known as ridges
G y r i
What divides the cerebrums into lobes also known as deep grooves
Fissures
It is associated with movement speech emotions and problem solving
Frontal lobe
It is associated with orientation perception of stimuli and recognition
Parietal lobe
Associated with the perception and recognition of the auditory stimuli memory and speech
Temporal lobe
Associated with a visual processing it is the site that delivers the visual processing
Occipital lobe
Receives emphasis from the bodies sensory receptors
Somatic sensory area
It sends impulses to skeletal muscles
Primary motor area
Involved in the ability to speak and it is located at the frontal lobe
Broca area
Located at the temporal lobe it enables the processing of words into coherent thoughts and recognition of the idea behind written or printed words
Wernickes area
Gustatory area
taste
Olfactory area
smell
Auditory area
hear
Visual area
sight
Composed mostly of cell neuron bodiess
The gray matter
fiber tracts inside the grey matter
The white matter
The internal island of the gray matter
Basal nuclei
What controls the speech?
Broca’s area
It sits on the top of the brain stem and it is enclosed by the cerebral hemisphere
Diencephalon
It contains the thalamus, hypothalamus, epithalamus
Diencephalon
It contains the thalamus, hypothalamus, epithalamus
Diencephalon
Surrounds the turn ventricle and is the relay station for impulse
thalamus
Transfer impulses to the correct part of the cortex location and interpretation
thalamus
Is it is under the thalamus and it is an important autonomic nervous system
hypothalamus
It helps regulate body temperature control water balance and regulate metabolism
hypothalamus
AN IMPORTANT PART OF THE LIMBIC SYSTEM AND THE PITUITARY GLAND IS ATTACHED TO IT
HYPOTHALAMUS
It forms the roof of the third ventricle and holds the pineal body from the endocrine
epithalamus
It forms the roof of the third ventricle and holds the pineal body from the endocrine
epithalamus
It forms the cerebrospinal fluid
Choroid plexus
It is attached to the spinal cord
Brain stem
It includes the midbrain pons and medulla oblonggata
Brain stem
Mostly composed of tract nerve fibers and the site for reflex impulse for hearing visual
midbrain
Bulging part of the brain stem, it involves nuclei in breathing
Pons
Initiate basic drives such as hunger aggression sexual arousal and emotional drive
Limbic system
Screens all messages traveling back to the cerebral cortex
Limbic system
It diffuses must part of the gray matter with the brain stem it involves the motor visceral organs and it is involved in the sleep wake cycle and consciousness
Reticular activating system
Two hemispheres withh consulted surfaces
cerebellum
iT involves the involuntary coordination of movements
cerebellum
Oxygenating the brain with ** four major arteries to vertebrals and two carrotid** to supply the brain with oxygenated blood
oxygenation
