AP PSYCHOLOGY

Detailed explanation-1: -Interneurons within your brain and spinal cord communicate with one another and process information between the sensory input and motor output.

Detailed explanation-2: -A special cell called a neuron is responsible for carrying these messages. There are about 100 billion neurons in the human brain. A neuron has three main parts. The cell body directs all activities of the neuron.

Detailed explanation-3: -Both sensory input and motor output signals are carried through nerves, which are long ropelike structures made from nerve cells. Nerve cells are two types – neurons and glia. Neurons are the cells which actually carry through signals whereas glia cells provide supporting structures and maintenance of neuronal cells.

Detailed explanation-4: -Efferent neurons are mainly located in the peripheral nervous system, but their cell bodies orginate in the CNS. Many incoming signals from the CNS converge onto the efferent neurons, which then affect the outgoing signals to various organs in the body. These organs then carry out the appropriate response.

Detailed explanation-5: -Nerve cells communicate using electrical and chemical signals.
