Brushing Hair

1. Brushing Hair Tracing The Transmission of Nerve Impulses Through The Body

2. Brushing hair begins with a visual stimulus. Most of the time, you will notice that your hair is not the way you like it. So, you get the feeling to brush your hair to make it the way you want it. Stimulus A stimulus is something that human sensory receptors are able to detect.

Sensory Receptors These are located all over the body, but some types of receptors are in specific areas of the body. Example: Taste receptors are located in the mouth.

Telling the brain that the muscles in the arms and fingers need to be used to brush the hair. Sensory Neurons Converts external stimuli from the environment to internal stimuli.

5. http://theathletescorner.com/?p=75 • The information received from the Sensory Neurons is further transmitted by relay neurons within the C.N.S. Once the information of brushing your hair reaches the C.N.S., it is then processed by the brain. Central Nervous System Part of the nervous system that integrates the information that it receives from, and coordinates the activity of, all parts of the bodies of bilateral animals.

6. http://www.mindcreators.com/NeuronBasics.htm • Starting with the axon, the neuron sends an electrical impulse of data through the arms. The axons sends information to the dendrite of another neuron through the synapses. Once another neuron receives this impulse, the dendrites send this information to the nucleus of the neuron and then send more information down its axon all to be processed again by the next neuron. Neuron A cell that can process and transmit information by electrical and chemical signaling.

They are packaged into synaptic vesicles clustered beneath the membrane on the pre-synaptic side of the synapse and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Neurotransmitter Endogenous chemicals that transmit signals from a neuron to a target cell across the synapse.

Motor Neuron Neurons located in the C.N.S. that project their axons outside the C.N.S. and can directly or indirectly control muscles.

Effector A nerve ending that carries impulses to a muscle or organ and activates muscle movements.
