Neuron Basics
This is the largest part of a neuro and serves as its life support center.
What is the soma (cell body)?
This is an automatic response to a stimulus that does not require conscious thought.
What is a reflex?
This is considered the dominant sense in humans.
What is vision (sight)?
These are the three main sections of the ear.
What are the outer ear, middle ear, and inner ear?
This is the scientific study of the endocrine system.
What is endocrinology?
These are the three main structural parts of a neuron.
What are the soma, dendrites, and axon?
These neurons carry information from sensory receptors to the central nervous system.
What are sensory neurons?
This is the scientific name for the sense of taste.
What is gustation?
This part of the eye changes size to control how much light enters.
What is the iris?
These are the two main chemical classes of hormones.
What are amino acid-based hormones and steroid hormones?
This is the typical voltage of a neuron when it is at resting membrane potential.
What is -70 millivolts?
This division of the autonomic nervous system is responsible for "fight or flight."
What is the sympathetic nervous system?
These types of receptors are responsible for both taste and smell.
What are chemoreceptors?
This tube connects the nasopharynx to the middle ear and helps equalize pressure.
What is the Eustachian tube?
This type of stimulus causes hormone release in response to changing ion or nutrient levels in the blood.
What is a humoral stimulus?
This type of potential occurs when a stimulus is not strong enough to trigger an action potential.
What is graded potential?
This is the largest part of the brain, making up about 83% of its total mass.
What is the cerebrum?
What is the lacrimal apparatus?
Sound travels through the air in this form before being converted to nerve signals.
What are mechanical waves?
This occurs when one hormone cannot exert its full effect without another hormone present.
What is permissiveness?
This disease involves the destruction of the myelin sheath in the central nervous system.
What is multiple sclerosis?
This gap between Schwann cells allows nerve impulses to jump along the axon more quickly.
What is the node of Ranvier?
This inner ear structure is essential for balance and equilibrium.
What is the vestibule?
What is the middle ear (tympanic cavity)?
This brain structure links the nervous and endocrine systems and is sometimes called the master endocrine gland.
What is the hypothalamus?
