General Nervous System
What are the two main types of nervous systems?
Central and Peripherial
Where is the nucleus located in a neuron?
Cell Body (soma)
What is the PNS?
Nervous system outside of the brain and spinal cord.
What are the main structures in the CNS?
Brain and Spinal Cord
What are the four lobes of the Brain?
Frontal, Temporal, Occipital, Parietal
What is the function of the Nervous system?
A system that transmits nerve impulses throughout the body to promote movement, involuntary movement, production of hormones, and the activation of glands.
What is a neuron?
Transmit electrical messages from one part of the body to other parts of the body.
What are the two systems within the PNS?
Autonomic system and Somatic system
Parasympathetic and Sympathetic
What is the relay center of the brain?
Thalamus
What are the cells within the Nervous system?
Neurons
What are the three types of neurons?
Motor, Sensory, Interneuron
What are the functions of the PNS?
Convery motor commands, carry sensory information, and regulating autonomic functions.
What four structures are your brain divided into?
Cerebrum, Brain stem, Cerebellum, Thalamus
What is a fight or flight response?
Heart rate, blood pressure, blood glucose levels, and oxygen intake from lungs increase to give more energy for a response.
What are the three structures that neurons exists as?
Bipolar, Unipolar, Multipolar
What does the somatic system do?
Nerves that go to the skin and the muscles.
What does the sympathetic system do?
flight-or-fight response
What are the functions of the brain stem?
Digestion, Circulation, Breathing
What is a stroke?
Blood circulation to the brain is being blocked and vital brain tissue dies.
Dendrite, Soma, Axon
What does the autonomic system do?
Connects the CNS to the visceral organs (heart, stomach, intestines)
What does the parasympathetic system do?
Initiates rest-and-digest responses and feed-and-breed responses.
What are the main functions of the four parts of the brain?
Cerebrum: Initiation of movement, coordination of movement, temperature, touch, vision, hearing, judgment, reasoning, problem-solving, emotions, and learning.
Cerebellum: Balance
Brain stem: Breathing and heart rate
Thalamus: Relays sensory and motor signals
