Nervous System
Part of nervous system that processes information, "CNS"
What is the Central Nervous System?
This lobe of the brain is responsible for voluntary movements and social understanding
What is the frontal lobe?
This is the name of what happens when you stop sensing a particular stimulus after a while
What is sensory adaptation?
This is the type of eye cell responsible for color vision
What are cones?
A scent travels to these nerves before travelling to the brain
What are olfactory nerves?
Part of the nervous system that regulates involuntary functions, "ANS"
What is the autonomic nervous system?
This lobe of the brain is responsible for processing of visual information
What is the occipital lobe?
This is the density of nerve endings found in the fingertips, lips and tongue
What is high density?
This vision cell detects the amount of light received; is in the retina
What are the rods?
These are the tiny bumps the cover the tongue and contain taste buds
What are the papillae?
Part of the nervous system that controls voluntary skeletal muscle movements and sensory input, "SNS"
What is the somatic nervous system?
This lobe of the brain is responsible for processing auditory information and understanding language
What is the temporal lobe?
This is the phase of an action potential when the stimulus opens sodium channels and causes a wave to travel down the neuron
What is depolarization?
This is the clear, thin layer that covers the sclera and lines the eyelids
What is the conjunctiva?
The function of this is to regulate balance through the movement of fluid in the semicircular canals
What is the vestibular system?
The three main functions of the nervous system
What is sensation, integration and response?
This part of the brain is responsible for balance and coordination; contains 50% of the neurons of the body
What is the cerebellum?
This neurotransmitter is responsible for regulating mood, involved in reward and motivation
What is dopamine?
These bones include the malleus, incus and stapes and transfer sound vibrations from the eardrum to your inner ear
What are the ossicles?
This gland of the endocrine system is called the "master gland" because it controls the other glands
What is the pituitary gland?
This organ is part of the CNS and is responsible for reflex actions
What is the spinal cord?
This part of the brain contains the midbrain, pons and medulla oblongata, controls sleep and wakefulness
What is the brain stem?
This is the part of a neuron where a neurotransmitter is released and captured by one or more dendrites
What is a synapse?
This structure in the inner ear converts sound into electrical signals
What is the cochlea?
This type of feedback system keeps a particular reaction going because the stimulus causes the action, which then causes the stimulus again
What is a positive feedback system?
