VAGUS NERVE
BRANCHING
Pharyngeal branches: this branches arise from the inferior ganglion of CN X. it contains
superior laryngeal nerve: this branches located in between the external and internal carotid arteries, it is divided into internal and external branches
recurrent laryngeal nerve: recurrent laryngeal nerve: The right recurrent laryngeal nerve’s fibers branch from the vagus nerve near the right subclavian artery, traveling superiorly to fibers branch from the vagus nerve near the right subclavian artery, traveling superiorly to enter the larynx between the cricopharyngeus muscle and the esophagus. The left recurrent laryngeal nerve then loops around the aortic arch distal to the ligamentum arteriosus and then enters the larynx.
superior cardiac: it gives off the superior cardiac nerve and is associated with parasympathetic fibers and travels to the heart.
FUNCTIONS
responsible for the regulation of internal organ functions such as digestion, heart rate, respiratory rate, and vasomotor activity.
responsible for certain reflex action such as coughing, sneezing, swallowing, and vomiting
TOPOGRAPHY
The vagus nerve, historically cited as the pneumogastric nerve, is the tenth cranial nerve or CN X. The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body
HYPOGLOSSAL NERVE
BRANCHING
meningeal branches: this branches arise from C1 and C2 nerves to the posterior cranial fossa
descending branches: it carries information from C1 and then C2 or C3 to innervate the neck muscle
thyrothyroid Branches: innervate the thyrohyoid muscle of the neck. The descending and thyrohyoid branches mostly originate from the cervical plexus.
Muscular Branches: only the muscular branch is considered part of the real hypoglossal nerve originating from the hypoglossal nucleus
FUNCTIONS
responsible for the regulation of internal organ functions such as digestion, heart rate, respiratory rate, and vasomotor activity.
responsible for certain reflex action such as coughing, sneezing, swallowing, and vomiting
TOPOGRAPHY
The Hypoglossal Nerve is the 12th Cranial Nerve (Cranial Nerve XII). It is mainly an efferent nerve for the tongue musculature. The nerve originates from the medulla and travels caudally and dorsally to the tongue
GLOSSOPHARYNGEAL NERVE
BRANCHING
tympanic nerve: it carries parasympathetic fibers, it exits the skill via the foramen ovale and synapses in the otic ganglion
stylopharyngeal nerve: provides motor innervation to the stylopharyngeus muscle
The nerve to carotid sinus: communicates with the vagus nerve to carry signals from the baroreceptors in the carotid sinus and chemoreceptors in the carotid body
pharyngeal branches: it forms the pharyngeal plexus
tonsillar branches: provide sensory innervation to the palatine tonsil
lingual branches: supply the vallate papillae, mucous membrane, and follicular glands of the posterior tongue
FUNCTIONS
carries sensory, efferent motor, and parasympathetic fibers
it control muscle in the oral cavity and upper throat
sense of tase
produce saliva
TOPOGRAPHY
The glossopharyngeal nerve is the ninth (IX) of the twelve pairs of cranial nerves. It exits the brainstem out from the sides of the upper medulla, just rostral to the vagus nerve and has sensory, motor, and autonomic components

Ganglion
Sensory
The sensory ganglia have an oval-like shape. Sensory ganglia are cell bodies with circular nuclei that are found in the dorsal roots of spinal nerves and the roots of some cranial nerves (ex. trigeminal nerve). The peripheral nervous system is connected to one section of these sensory ganglia. The brain or spinal cord connects the other half to the central nervous system.
Motor
From the base of the skull to the tail end of the spine, the motor ganglia form a lengthy chain. They have cell bodies that are irregularly formed. The autonomic nerve system includes motor ganglia. The autonomic nervous system (ANS) is in charge of involuntary motions and processes, such as breathing. The motor ganglia can be found in the following places: Internal organs and the spinal cord. The paravertebral ganglia are found in the spinal cord. Organs inside the body: Prevertebral ganglia and terminal ganglia are two types of ganglia.
Nerve
Nerves are bundles of axons that run through the PNS.
These structures at the peripheral differ from their core equivalent, which is known as a tract.
Nerves are made up of more than simply neural tissue; they also comprise connective tissues and blood arteries in their structure that provide sustenance to the tissues.
The epineurium is a fibrous connective tissue layer that surrounds a nerve's outer surface.
Axons are further bundled into fascicles within the nerve, each of which is surrounded by its own layer of fibrous connective tissue termed perineurium.
Finally, the endoneurium is a loose connective tissue that surrounds individual axons.
The connective tissue sheaths for muscles are identical to these three layers.
Axons that have been cut can regrow because they are surrounded by an endoneurium.
The proximal severed end of the axon sprouts, and one of the sprouts will discover the endoneurium, which is simply an empty tube heading to (or near) the original target, after they have been cut.
The distal section of the severed axon degenerates, leaving the endoneurium empty. This is known as Wallerian (anterograde or orthograde) degeneration.
Nerves are named for the CNS area to which they are attached, such as cranial nerves that run through the brain or spinal nerves that run through the spinal cord.
