The brachial plexus supplies motor and sensory innervation to the upper limb. It is formed by the ventral rami of the spinal nerves C5-T1, and its branches include the musculocutaneous, median, ulnar, radial, and axillary nerves. These nerves control the muscles and provide sensation to the shoulder, arm, forearm, and hand.
Genetic recombinations of DNA cause variations of genetic traits .
You are speaking of the 12 cranial nerves:I. Olfactory nerve which branches out of the telencephalonII. Optic which branches out of the diencephalonIII. Oculomotor nerve which branches out of the mesencephalonIV. Trochlear nerve nerve which branches out of the mesencephalonV. Trigeminal nerve which branches out of the ponsVI. Abducens nerve which branches out of the ponsVII. Facial nerve which branches out of the ponsVIII. Vestibulochochlear nerve which branches out of the ponsIX. Glossopharangeal nerve nerve which branches out of the medullaX. Vagus nerve nerve which branches out of the medullaXI. Accessory nerve nerve which branches out of the medulla & cervical spineXII. Hypoglossal nerve nerve which branches out of the medulla
The autonomic nervous system consists of the sympathetic and parasympathetic branches that regulate the heart rate. The sympathetic nerves release neurotransmitters such as norepinephrine to increase heart rate, while the parasympathetic nerves release acetylcholine to decrease heart rate.
No, the sciatic nerve is not formed by three separate nerves wrapped in connective tissue. It is a single nerve that originates from the lumbosacral plexus, primarily formed by the L4 to S3 spinal nerves. The sciatic nerve is the largest nerve in the body and branches into the tibial and common peroneal (fibular) nerves.

Nerves are like trees. The have branches call axons.
Anterior branches of thoracic spinal nerves.
There are more than 3 nerves in the cervical plexus. The most important nerve here is the phrenic nerve, which supplies the diaphragm, from roots C3-5. Other deep branches include the ansa cervicalis and segmental branches; the superficial branches are the lesser occipital, great auricular, transverse cervical and supraclavicular.
The brachial plexus supplies motor and sensory innervation to the upper limb. It is formed by the ventral rami of the spinal nerves C5-T1, and its branches include the musculocutaneous, median, ulnar, radial, and axillary nerves. These nerves control the muscles and provide sensation to the shoulder, arm, forearm, and hand.
The dorsal rami are small branches of spinal nerves that emerge from the spinal cord and supply the skin and muscles of the back. They are responsible for providing sensory and motor innervation to the back of the body.

The ventricular myocardium is supplied by branches of the left and right coronary arteries, which provide oxygen and nutrients to the heart muscle. These arteries receive autonomic innervation from the sympathetic and parasympathetic nerves, which modulate the heart's activity.
The sympathetic nervous system branches include the sympathetic trunk and the splanchnic nerves. The sympathetic trunk contains the sympathetic ganglia, which are responsible for sending signals to various target organs in the body. The splanchnic nerves innervate the abdominal organs and play a role in regulating their function.
