TRUE
Part of the brain that controls reasoning, decision making and planning
What is the frontal lobe?
Part of the eye that does not have the job of regulating or focusing light as it comes into the eye
What is the Sclera?
Sends impulse from the senses to the CNS
What is sensory division ( Afferent )
Provide myelin insulation to neuron
What are Schwann cells?
Encapsulated nerve endings that detect deep pressure an vibrations
What are Pacinian Corpuscles?
Portion of the brain that is responsible for involuntary activities such as posture, breathing and heart rate
photoreceptors in the center of the retina that detects color and is less sensitive?
what are cones?
Reduces a sympathetic response and provided resting functions (rest and digest)
What is the Parasympathetic division?
Cell is negatively charged and the environment is positively charge
what is resting potential?
what is Chemoreceptors?
what is the thalamus, hypothalamus and pineal gland?
what is the fovea centralis?
The cells that mostly make up the nervous system
What is neuroglia?
Where two neurons meet
What is a synapse?
Senses touch and pressure
what are Mechanoreceptors?
made up of gray matter and made up of cell bodies and dendrites
what is the cerebral cortex?
converts waves into impulses
what is the Organ of Corti?
Classified by the number of processes extending from the cell body
What is a neuron?
Correct order for transmission of the impulse as it passes what through a neuron
Dendrites--> cell body--> axon
The five majorly type of sensory receptors
What are chemoreceptors, photoreceptors, thermoreceptors, mechanoreceptors, and pain receptors?
Deep groove that separates the large portions of the brain
What's fissure?
Correct order in which sound waves flow through the ear
auricle, auditory canal, tympanic membrane, ossicles, cochlea
