The cervical plexus is a plexus of the ventral roots of the first four cervical spinal nerves which are located from C1 to C4 cervical segment near the neck. They are located laterally to the transverse processes between prevertebral muscles from the medial side and vertebral(m.scalenus,m.levator scapulae,m.splenius cervicis) from lateral side. Here there is anastomosis with n.accessorius, n.hypoglossus and sympathetic trunk. It is located in the neck, deep to sternocleidomastoid. Nerves formed from the cervical plexus innerva ...

The 12 cranial nerves originate from the brainstem, and mainly control the functions of the anatomic structures of the head with some exceptions. CN X receives visceral sensory information from the thorax and abdomen, and CN XI is responsible for innervating the sternocleidomastoid, or musculus sternocleidomastoideus and trapezius muscle, or the musculus trapezius, neither of which are exclusively in the head. Spinal nerves take their origins from the spinal cord. They control the functions of the rest of the body. In humans, there ar ...

The ansa cervicalis is a loop of nerves that are part of the cervical plexus. The superior root of the ansa cervicalis is a loop between fibers from spinal nerves C1 and C2. These nerve fibers travel in the hypoglossal nerve before leaving to form the superior root. The superior root goes around the occipital artery and then descends in the carotid sheath. It sends a branch off to the superior belly of the omohyoid muscle and is then joined by the inferior root. The inferior root is formed by fibers from spinal nerves C ...

Cervical vertebrae (Vertebrae cervicales) are the smallest of the true vertebrae, and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process. The first, second, and seventh cervical vertebrae present exceptional features and must be separately described, though the other four have common characteristics. Cervical vertebrae - General characteristics. These are the general characteristics of the third through sixth cervic ...

Chakras are in the Linga Sarira (astral body). Linga Sarira is of 17 Tattvas, viz., 5 Jnanendriyas (ears, skin, eyes, tongue and nose); 5 Karmendriyas (speech, hands, legs, genitals, anus); 5 Pranas (Prana, Apana, Vyana, Udana, Samana); Manas (mind); and Buddhi (intellect). These have corresponding centres in the spinal cord and the nerve-plexuses in the gross body. Each Chakra has control and function over a particular centre in gross body.

Four Asanas are prescribed for the purpose of Japa and meditation. They are Padmasana, Siddhasana, Svastikasana and Sukhasana. You must be able to sit in any one of these four Asanas at a stretch for full three hours without shaking the body. Then only you will get Asana-Jaya, mastery over the Asana.

From "Kundalini Yoga" by Sri Swami Sivananda

The accessory nerve (or "Spinal accessory nerve") is the eleventh of twelve cranial nerves. It leaves the cranium through the jugular foramen along with the glossopharyngeal nerve (IX) and vagus nerve (X). It innervates the sternocleidomastoid muscle (sternomastoid) and trapezius muscle on the ipsilateral side. There are two parts to the accessory nerve, a spinal part (innervates the muscles around neck), and a cranial part, that splits off, and quickly combines with the vagus nerve. The cranial part of nerve XI can b ...

In anatomy, ribs (Latin costae) are the long curved bones which form the rib cage. Ribs surround the chest (Latin thorax) of land vertebrates, and protect the lungs, heart, and other internal organs of the thoracic cavity. In mammals, one generally thinks of ribs only occurring in the chest. However, fused-on remnants of ribs can be traced in development in neck vertebrae and sacral vertebrae. In reptiles, ribs sometimes occur in all vertebrae from the neck to the sacrum. Fish can have up to four ribs on each vert ...

The autonomic nervous system is the part of the nervous system of the higher life forms that is not consciously controlled. It is commonly divided into two usually antagonistic subsystems: the sympathetic and parasympathetic nervous system. The autonomic nervous system controls such vital functions as heart rate, dilation of the bronchioles and dilation and constriction of the pupil; the digestive tract is controlled almost completely by autonomic mechanisms.

Its parasympathetic fibers reach the geniculate ganglion but do not synapse. Some of these preganglionic parasympathetic fibers persist within the greater petrosal nerve as they exit the geniculate ganglion and subsequently synapse with neurons in the pterygopalatine ganglion. These postganglionic neurons send axons that provide parasympathetic innervation to the lacrimal gland. The remaining preganglionic fibers continue as the mixed facial nerve proper as it extends through the facial canal. Before the nerve exits the skull via the ...

The spinal cord originates inside the brain at the inferior end of the medulla oblongata, exiting the skull via the foramen magnum. It is wrapped in three layers of membranes, called meninges. The spinal cord carries sensory signals and motor innervation to most of the skeletal muscles in the body. Just about every voluntary muscle in the body below the head depends on the spinal cord for control. Similarly, most cutaneous sensation below the neck is transmitted via the spinal cord. Most of the sympathetic pathways and the lower (i.e. non-vagal) parasympathetic pa ...

The anterior divisions of the thoracic nerves (rami anteriores; ventral divisions) are twelve in number on either side. Eleven of them are situated between the ribs, and are therefore termed intercostal; the twelfth lies below the last rib. Each nerve is connected with the adjoining ganglion of the sympathetic trunk by a gray and a white ramus communicans. The intercostal nerves are distributed chiefly to the parietes of the thorax and abdomen, and differ from the anterior divisions of the other spinal nerves, in that each p ...

The human arm contains bones, joints, muscles, nerves, and blood vessels. Many of these muscles are used for everyday tasks. Arm - Bony structure and joints. The humerus is the (upper) arm bone. It joins with the scapula above at the shoulder joint (or glenohumeral joint) and with the ulna and radius below at the elbow joint. Main article: Shoulder The shoulder is the ball-and-socket joint between the proximal end of the humerus and the clavicle and scapula.

These are the general characteristics of the third through sixth cervical vertebrae. The first, second, and seventh vertebrae are extraordinary, and detailed later. The body of these four vertebrae is small, and broader from side to side than from front to back. The anterior and posterior surfaces are flattened and of equal depth; the former is placed on a lower level than the latter, and its inferior border is prolonged downward, so as to overlap the upper and forepart of the vertebra below. The upper surface is concave transversely, ...

The cranial sympathetics include sympathetic efferent fibers in the oculomotor, facial, glossopharyngeal and vagus nerves, as well as sympathetic afferent in the last three nerves. The Sympathetic Efferent Fibers of the Oculomotor Nerve probably arise from cells in the anterior part of the oculomotor nucleus which is located in the tegmentum of the mid-brain. These preganglionic fibers run with the third nerve into the orbit and pass to the ciliary ganglion where they terminate by forming synapses with sympathetic motor neurons whose ...

Sphenoid bone - Surfaces. The superior surface of each is flat, and supports part of the frontal lobe of the brain.
