GENERAL HISTOLOGY

Detailed explanation-1: -The cell bodies of the sensory neurons are in the dorsal root ganglion, but the motor neuron cell bodies are in the gray matter. The two roots join to form the spinal nerve just before the nerve leaves the vertebral column. Because all spinal nerves have both sensory and motor components, they are all mixed nerves.

Detailed explanation-2: -Mixed cranial nerves are a group of cranial nerves that consist of sensory and motor nerve fibers. There are four such nerves in our peripheral nervous system namely the Trigeminal nerve (CN V), Facial nerve (CN VII) Glossopharyngeal nerve (CN IX), and Vagus nerve (CN X).

Detailed explanation-3: -Many nerves start in your spinal cord and some even from your brain. They extend throughout your body, including in your: Arms, including your ulnar nerve, median nerve, radial nerve and axillary nerve. Chest and abdomen, including your vagus nerve and phrenic nerve.

Detailed explanation-4: -There are three types of nerves in the human body which are classified based on their functions. These are the sensory nerves, motor nerves and mixed nerves.

Detailed explanation-5: -A mixed nerve is any nerve that contains both sensory (afferent) and motor (efferent) nerve fibres. All spinal nerves are mixed nerves. Some cranial nerves are mixed nerves.
