The Nervous System
Amarilis Ramos Period 2
Major Functions of the Nervous System
Major Divisions and Subdivisions
to help process the sensory input in our body
respond to any type of activity occurring
To collect sensory inputs from the human body
Major Parts of the Brain and Functions
Name of the Lobes and Functions
Tissue(structures and function of a neuron)
The layers of the Meninges

Spaces and Ventricles of Brain
Classification of the Neuron ;major parts and functions of the spinal cord
Action Potential and Drugs that affect the brain
Diseases that associated with the brain
Major nerves of the body division of the PNS of body
Sensory
Motor
Somatic
Anatomy of the spinal cord covering Neurotransmitters
Cranial nerves
Spinal Nerves
Compare and Contrast the autonomic nervous system
Major divisions
Subdivisons
Central Nerve -a part in which consist of the brain and the spinal cord
Peripheral Nerve-a nerve in our body that helps with the outside of the brain and spinal cord
Somatic nerve-voluntary movement within our bodies
Autonomic Nerve-involuntary control of the body regulating our heart and other parts
Sympathetic fiber-help increase energy in our body
Parasympathetic fiber -conserves are energy
Parkinson's disease-a disease that come from dopamine that release neurons
Huntington's disease-a disease in the nuclei that kills the tissues
Alzheimer 's Disease-a process that degenerative the brain and affects speech
Occipital Lobe-the part of our brain that has to do with being able to help us visualize things
Pariental Lobe-the main part of the body that has to do with our sense of taste
Frontal Lobe-helps with the ability of speech and is the main area in our body
Temporal Lobe-the area that helps sensory speech the way we sense things in our brain
Its importance is to help the process of breathing compares to another system in our body like Cardiac System.
This can contrast ti bit providing enough digestion that can lead to problems.

Marijuana -Dopamine receptors ,Dopamine neurotransmitters
Methamphetamine-affects our Dopamine Neurotransmitters.
Ecstasy-Affects Serotonin.Neurotransmittters
Alcohol-affect the GABA Inhibitory and Dopamine
Cocaine-affects the Dopamine ,Serotonin,and norepinephrine
Heroine -a drug that affects the receptors ,Neurotransmitter ,Dopamine,and etc.
LSD-affects our Serotonin
Action Potential-a potential in our body that reacts and creates an impulse along the membrane of muscle cells
3 main neurons
Motor neurons-function is to direct any type of control in our muscles
Interneurons-function is to allow communication to occur within our brain
Sensory neurons-function is to help with stimulate in our neurons
Function of spinal cord-help balance the way we stand correctly also helps with flexibilities motion and also can help to protect the different body organs
Third Ventricle
Fourth Ventricle
Cerebral aqueduct
Corpus Callosum
Central Canal
Lateral Ventricle)
Pituitary Gland-helps secrete any hormones in the bloodstream
Spinal Cord-help protect the organs within our bodies
Cerebellum-recievee information and help with movement in the brain
Brain Stem-helps with the control of messages to go around the brain
Cerebrum-Function is to provide us with the ability to think and reform actions
Pineal Gland-help to regulate hormones and not have them out of control
Axon-function is to transmit any information received to the other neurons in the body also muscles
Myelin Sheath-function is to protect the fibers from any problems
Nucleus-function is to help organize DNA and proteins to form chromosomes
Schwann's Cell-help keep nerve fibers alive and not die out.
Dendrites-function is to send messages to the cell body
Axon Terminals-function is to release neurotransmitters on cells
Cell Body-brings and carries information to the neurons
Node of Ranvier- function is to help conduct rapid connection of nerve fibers
Thoracic nerves
Lumbar nerves
Cervical Nerves
Sacral nerves
