Question	Answer
Unlike the parts of the nervous system, the endocrine systems parts are	physically connected
Thoughts, movements, and some life processes are controlled by the	nervous system
Something that causes your nervous system or endocrine system to produce a response is called a	stimulus
Which system transmits the message that you have a pebble in your shoe?	peripheral
When you compare the endocrine system to a satellite television system, a satellite dish is compared to a	receptor
The structure that carries electrical messages away from a neuron's cell body is called a	axon
What is a neuron's resting potential?	the difference in charge across the cell membrane
Which of the following describes how an action potential moves down an axon	Ion channels' gates open and close
What happens when an action potential reaches the axon terminal?	Vesicles release chemicals into the synapse
Which phase best describes a neurotransmitter?	A neurotransmitter is a chemical signal
Which nervous system uses interneurons that interact with other nerves in the body?	The central nervous system
Which part of the brain forms responses such as thought and movement?	cerebrum
Why does a reflex arc result in a very quick response?	because the impulse does not travel to the brain?
Which of the following is a function of your brain stem?	to coordinate your heart beat and breathing
The parasympathetic nervous system is activated when you	sit thinking
Which type of sensory receptor helps humans detect light?	photoreceptor
Target cells for a given hormone have the correct?	receptors
Hypothyroidism is a condition caused by a lack of hormones from the ?	thyroid gland
An electrical impulse moving down an axon is called?	action potential
Hair cells in the inner ear contain mechanoreceptors that detect?	vibrations
Both the nervous and the endocrine systems allow you to?	respond to stimuli
what happens to impulses generated by chemoreceptors in the nose and the mouth?	they are transmitted to the brain
which part of the eye contains the rods and cones?	retina
cells in the eye that contribute to black and white vision are	rods
what kind of receptors are the hair cells, which are found in the ear?	mechanoreceptors
how do the receptors in sensory organs help the body maintain homeostasis?	by gathering information from the environment
which cells detect chemicals dissolved in the nose?	olfactory
mechanoreceptors in the outermost layer of skin detect?	gentle touch
the endocrine system uses chemical signals called?	hormones
the most significant difference between the actions of steroid and nonsteroid hormones is	only steroid hormones pass through the cell membrane
hormones are released into the bloodstream by?	endocrine glands
which of the following acts as a part of both the nervous and the endocrine systems?	the hypothalamus
after the pituitary gland is stimulated by a releasing hormone, it will often?	release a hormone that stimulates another gland.
cells have receptors on the outside of their membranes. These receptors allow the cell to ?	interact with its outer environment.
which part of neurons carry messages to the cell body?	dendrites
the brain is connected to the spinal cord by the?	brain stem
nerve pathways that produce responses without involving the brain are called?	reflex arcs
which type of neuron relays signals from the central nervous system to the muscles?	motor neuron
in order for an adjacent neuron to generate an action potential, it usually needs to?	be stimulated at more than one synapse
form junctions with other cells' dendrites?	terminal axon
covers the axon of neurons?	myelin sheath
receives messages from other cells?	dendrites
passes messages away from the cell body to other neurons?	axon
the main part where the nucleus is located?	cell body
detect temperature?	thermoreceptors
sense extreme heat, cold, and pressure?	pain receptors
respond to light pressure, movement, and tension?	mechanoreceptors
detect light?	photoreceptors
detect chemicals that are dissolved in fluid?	chemoreceptors
