Answer:
CNS/PNC Differences
The central nervous system (CNS) and peripheral nervous system (PNS) are two major components of the nervous system. The CNS includes the brain and spinal cord, while the PNS consists of all the other nerves and ganglia that extend from the brain and spinal cord to various parts of the body.
The CNS acts as the main processing center for incoming sensory information and outgoing motor commands. The PNS, on the other hand, is responsible for transmitting sensory information from the body to the CNS and carrying motor commands from the CNS to the muscles and organs.
MN/SN Differences
Motor neurons and sensory neurons are two types of neurons found in the nervous system. Motor neurons are responsible for transmitting motor commands from the CNS to the muscles and organs, causing them to contract or relax. Sensory neurons, on the other hand, transmit sensory information from the body to the CNS, allowing us to perceive and respond to various stimuli.
Axons and dendrites are two types of specialized projections found on neurons. Axons are elongated structures that transmit information away from the cell body of the neuron to other neurons, muscles, or organs. Dendrites are shorter, branching structures that receive incoming information from other neurons and transmit it to the cell body. In other words, axons carry information away from the cell body, while dendrites receive information and carry it towards the cell body.
