| 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 |
