A plexus is a network. In biology it has two meanings. In many animals the processes of neurons join together to form a plexus or nerve net. This is the characteristic form of nervous system in the coelenterates and persists with modifications in the flatworms. The nerves of the radially symmetric echinoderms also take this form, where a plexus underlies the ectoderm of these animals and deeper in the body other nerve cells form plexuses of limited extent. In vertebrates nerves branch and rejoin in some parts of the body, for e ...

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 choroid plexus is the area on the ventricles of the brain where cerebrospinal fluid (CSF) is produced. Choroid plexus is present in the superior part of the inferior horn of the lateral ventricles. It follows up along this boundary, continuous with the inferior of the body of the lateral ventricles. It passes into the interventricular foramen, and is present at the top of the third ventricle. There is also choroid plexus on the fourth ventricle, on the ...

The brachial plexus is an arrangement of nerve fibres (a plexus) running from the spine (vertebrae C5-T1), through the neck, the axilla (armpit region), and into the arm. All nerves of the arm stem from the brachial plexus (with the exception of the intercostobrachialis nerve which supplies an area of skin near the axilla). Therefore, lesions of the plexus can lead to severe functional impairment. Brachial plexus - Anatomy. The brachial plexus starts from the five ventral rami of the spinal nerves, after th ...

The Solar Plexus Chakra

This chakra is radiating a blue-violet light, and also a golden light. When the solar plexus is pure, then one is at peace with others, then one lives a life without conflicts, where all relations are positive, and all conflicts are stopped and transformed into exiting confrontations, where one is learning instead of fighting.

Chakras: Manipura Chakra

Manipura chakra, the solar plexus center, is where the fire element presides. The whole gamut of heated emotions of jealousy, anger, vanity, belly laughter, and willful assertiveness is based here. Manipura is associated with the navel, and feelings of dependency and autonomy relate to it, as well as the psychological ideal of "emotional honesty."

Anahata Chakra is situated in the Sushumna Nadi (Sukshma centre). Anahata Chakra has control over the heart. It corresponds to the Cardiac Plexus in the physical body. This corresponds to Mahar Loka. Anahata Chakra is of deep red colour. Within Anahata Chakra there is a hexagonal space of smoke or deep black colour or the colour of collyrium (used for the eyes).

The xiphoid process is a small cartilaginous extension to the lower part of the sternum which is usually ossified in the adult human. By age 25 to 29, the xiphoid usually fuses to the body of the sternum with a fibrous joint. Unlike the synovial articulation of major joints, this is non movable. Much the way the first seven ribs articulate with the sternum, the cartilage in the solar plexus joins on the xiphoid process, reinforcing it, and ind ...

The upper limb is the professional term used to describe the region that laymen would usually call the "arm". In human anatomy, this area is defined as everything from: the shoulder the surrounding axilla muscles and structures supplied by the brachial plexus nerves the arm the forearm the wrist (carpal joint) and the hand.

In Japanese hand-to-hand combat and martial arts, atemi designate blows and hits, by opposition to twistings, strangleholds, holding technique and throws. Karate is a typical martial art focusing on atemi. Some strikes against vital parts of the body can kill or incapacitate the opponent: on the solar plexus, at the temple, under the nose, in the eyes, genitals, or under the chin. Most traditional Japanese martial arts (the ancestors of judo, jujutsu and aikido) do not focus on atemi very much, since they were supposed to be used on ...

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 ...

The ventricular system is a set of structures in the brain continuous with the central canal of the spinal cord. The system comprises four ventricles: right and left lateral ventricles, third ventricle, and fourth ventricle. Each ventricle contains a choroid plexus that produces cerebrospinal fluid (CSF) used to bathe and cushion the brain and spinal cord within their bony confines. Ventricular system - Ventricles. There are four cerebral ventricles: the paired lateral ventricles and the third and fourth ve ...

The ulnar nerve is a nerve that in humans runs down the arm and forearm, and into the hand. The ulnar nerve comes from the lower cord of the brachial plexus, and runs posterior to the humerus down the arm, going behind the medial epicondyle at the elbow. This part of the ulnar nerve is known as the funnybone for two reasons: because of its proximity to the humerus (and the similar word "humorous"), and because of the mild pain and tingling throughout the forearm associated with sudden compression of the nerve at this point (the label 'funnybone' is th ...

An artificial neural network (ANN), also called a simulated neural network (SNN) (but the term neural network (NN) is grounded in biology and refers to very real, highly complex plexus), is an interconnected group of artificial neurons that uses a mathematical or computational model for information processing based on a connectionist approach to computation. There is no precise agreed definition among researchers as to what a neural network is, but most would agree that it involves a network of highly complex processing ...

The fact that the nerves of the brachial plexus are grouped together acts as a benefit as well. Local anesthetics such as lidocaine or bupivacaine can be injected in close proximity to these nerves, rendering an entire arm insensate and immobile. The process of injecting local anesthetic for this purpose is called regional nerve blockade or more simply, a nerve block, and it is a common procedure in anesthesia. After an onset time of approximately 10 to 15 minutes, the targeted arm will be fully anesthetized and ready for surgery. The patien ...

The brachial plexus starts from the five ventral rami of the spinal nerves, after they have given off their segmental supply to the muscles of the neck. These are the five roots. These roots merge to form three trunks: "superior" or "upper" C5-C6, "middle" C7, and "inferior" or "lower" C8-T1. Each trunk then splits to form an anterior and a posterior division. These six divisions will regroup to become the cords. The cords are named by their position in respect to the axillary artery. The posterior ...

The last 4 cervical spinal nerves, C5 through C8, and the first thoracic spinal nerve, T1,combine to form the brachial plexus, or plexus brachialis, a tangled array of nerves, splitting, combining and recombining, to form the nerves that subserve the arm and upper back. Although the brachial plexus may appear tangled, it is highly organized and predictable, with little variation between people. See brachial plexus injuries. See also:

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 ...
