What is Synapse ?
Releases from the axon of the previous neuron
A gap between the axon of the neuron & dendrite
Releases a neuron transmitter that tells the muscle how to react
Sends impulse straight to the motor neuron
What are the functions of the Nervous System ?
Monitor the body’s internal & external environment
Integrate information from each of the sense
Coordinate voluntary & involuntary muscles, & organ function
Regulates involuntary smooth & cardiac muscle as well as glands
The Neural Tissue includes
What does the sensory neurons do ?
Carry signals from the central nervous system to muscles or organs
Connect neurons to other neurons
Receive information from the sensory neurons of the peripheral nervous system
A thin covering around the entire axon
Sensory neuron picks up a
(a)
What are the steps of Reflex Arc ?
Sensory Neuron - picks up a stimulus
Axon - sends stimulus through the neuron to the info the interneuron
Interneuron - sends impulse straight to motor neuron
Motor Neuron - released a neuron transmitter that tells muscles how to react
What does the Central Nervous System include ?
Spinal Cord
Muscles
Brain
Brain & Spinal Cord
Integrates sensory information
(a)
The first layer of the protection are the flat bones of the skull
(a)
The Cerebrum
Contains the vision center
Contains neuron cells bodies
Controlling conscious thought, complex movements, & memory
Coordinates & regulates muscular activity
Contains the auditory, taste, & olfactory areas
(a)
What is a concussion ?
Ringing in the ear
Trauma-induced alteration in mental status that may or may not involve loss of consciousness
Loss of memory that happened before the concussion
Sensitive to light
What is Anterograde Amnesia ?
Loss of memory of events that happened before the concussion
Loss of balance
Loss of memory of events that happened after the concussion
Slurred speech
What is Cerebrospinal Fluid ?
Provides a watery cushion that protects nervous tissue from trauma
the innermost layer
outermost thickest layer
Membranes of connective tissue
What do Rods detect ?
Color
Light
Incoming light
Produces tears
What do Cones detect ?
Tears
Color
Fluid
What is the pathway of vision ?
Cornea - Refracts/bends incoming light
Light passes through an opening in the iris ( pupil)
As the light hits the lens, the light is refracted even further to help the eye focus & image is flipped
Fovea Centralis
Eardrum vibrated from the sound waves to detect sound
(a)
Chemicals dissolved in saline activate the microvilli
(a)
