the bio-electrical signals conducted by nerve cells ar known as neural impulse
the ______ nervous system controls involuntary actions and actions of the internal organs autonomic
the ______ nervous system is responsible for voluntary movements and the senses somatic
conditions or events that cause the body to react are called stimuli
the _____ nervous system consists of the brain and the spinal cord central
chemical messengers that relay impulses across nerve junctions are called neurotransmitter
the ____ nervous system consists of all nerves outside the brain and the spinal cord peripheral
the 12 pairs of nerves that emerge directly from the brain are collectively called cranial nerves
what kind of actions are controlled by the somatic nervous system? voluntary
which nerves carry light impulses from the retina to the brain? optic nerves
which nerves carry sound impulses from the inner ear to the brain? auditory nerves
name the thick collumn of nervous tissue that connects the brain to all parts of the body spinal cord
what kind of actions are controlled by the autonomic nervous system? involuntary
which nerves carry smell impulses from receptors in the nose to the brain? olfactory nerves
the 31 pairs of nerves that emerge from the spinal cord segments are collectively called: spinal nerves
what type of response protects your hand when it touches a hot surface? reflex
that part of the brain controls the balace and coordinates body movement? cerebellum
the right hemisphere of the brain controls whcih side of the body? left
a neuron that carries signals from the brain to the muscles to control movement is called motor neuron
a neuron that carries stimuli impulses to the brain or spinal cord is termed as sensory neuron
heartbeat,breathing,and digestion are controlled by which nervous system? autonomic
what part of the brain controls thought, voluntary movement,language and reasoning? cerebrum
the left hemishphere of the brain controls which side of the body? right
chemical messengers that relay electrical impulses across a synapse are called neurotransmitter
name the tiny gap between nerve fibers where impulses pass from one neuron to another synapse
what is the scientific term for a nerve cell-cell that conducts bio-electrical signals neuron
neuron that carries stimuli impulses to the brain or spinal cord is termed as: sensory neuron
nerve ending that recognizes a stimulus in the environment and converts it into a signal sensory receptor
short bushy fibers of a neuron that recieve impulses from other neurons are called dendrite
long extension of a nerve call that carries impulses to other neurons,muscles,or glands axon
what part of the brain controls hunger,thirst, body temp.,and sleep cycle hypothalamus
name the three protective membranes that cover the brain and spinal cord meninges
name the part at the top of the spinal cord that controls the body's involuntary actions brain stem
what specific part of the brain controls breathing,heart rate, and blood pressure medulla
name the large band of neural fibers that connects the two brain hemispheres corpus callosum
protective cushion of liquid that circulates in the brain and spinal cord cerebrospinal fluid
progressive disease that destroys brain cells and causes muscular tremors and rigidity parkinson's disease
brain disorder resulting in gradual loss of memory,reasoning,language& physical functioning alzheimer's disease
abnormal growth of brain tissue that can compress and destroy healthy brain tissue brain tumor
swelling of the brain due to water retention usually causing unconsciousness cerebral edema
injury to the brain caused by sudden impact, usually causing unconsciousness concussion
infection & inflammation of the protective membranes covering the brain and spinal cord meningitis
central nervous system disorder characterized by loss of consciousness and severe convulsions epilepsy
damage to brain tissue due to sudden bleeding or blockage of blood vessels in the head stroke
endocrine glands secrete directly into what area of your body blood stream
to produce a response, what do hormones bind to on the surface of target cells receptors
feedback mechanism that steadily increases hormone levels during stimuli is called positive feedback
feedback mechanism that maintains hormone levels within is narrow ranges is called negative feedback
diabetes, a common disease, is a disorder of which endocrine gland pancreas
An example of a slow-acting hormone is human growth hormone
the chemical product of an endocrine gland is called hormone
