cone

• a nerve cell that sends information from the brain or spinal cord to a muscle or gland

• a photoreceptor in the eye that distinguishes color and detects fine details in bright light

• the part of the nervous system that carries information between the brain and other parts of the body

dendrite

• mechanical stimulation of the skin

• a region of the brain related to memory

• a branch that extends from a neuron’s cell body and receives incoming information

interneuron

• a nerve cell that sends information from sense receptors to the brain

• a photoreceptor in the eye that becomes active in dim light

• a neuron that connects sensory and motor neurons

cerebral cortex

• a cell that collects information to send to the brain for interpretation

• the time it takes for a stimulus to produce a response

chemoreceptor

• a region of the brain related to memory

• a chemical that is released when an electric impulse reaches the end of a neuron’s axon; transmits the signal to the dendrites of the next neuron

• a sensory cell that responds to a chemical stimulus

axon

• a region of the brain related to memory

• the perception of pressure, temperature, or pain experienced through the skin

• a thin and usually long extension of the neuron that carries impulses away from the cell body

amygdala

• a region of the brain involved in emotional memory, such as fear

• mechanical stimulation of the skin

• a nerve cell that sends information from sense receptors to the brain

photoreceptor

• a sensory cell that responds to visible light in the electromagnetic spectrum

• a branch that extends from a neuron’s cell body and receives incoming information

• one of the four main lobes of the cerebral cortex where memories are stored and language processed

nervous system

• a photoreceptor in the eye that becomes active in dim light

• the system that controls all the activity inside the body, and monitors and responds to the outside environment

• mechanical stimulation of the skin
