Cell Bodies of Sensory Neurons
Autonomic ganglia contain the cell bodies of motor neurons.
Dorsal root ganglia of the spinal chord gray matter.
Autonomic ganglia contain the cell bodies of motor neurons.
Sensory neurons: Transmit sensory information from the body to the brain. Motor neurons: Control muscles and glands, enabling movement and bodily functions. Interneurons: Process information within the central nervous system, facilitating communication between sensory and motor neurons.
Paravertbral ganglia (aka sympathetic trunk ganglia)
cell bodies of unipolar neurons
The two parts of the peripheral nervous system are somatic and visceral. P.S.- The former innervates the skin,joints and muscles whereas the latter to the internal organs, blood vessels and glands. The latter is divided into sympathetic and parasympathetic (like the reins of a horse).
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS
