Among all different types of photography showcased on the Smashing Magazine, **underwater photography** is probably one of the most difficult ones. It requires a very specialized equipment and the knowledge of some advanced techniques to get a perfect picture.
Anatomical terms of neuroanatomy. A nerve plexus is a plexus (branching network) of intersecting nerves. A nerve plexus is composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses, except in the thoracic region, as well as other forms of autonomic plexuses, many of which are a part of the enteric nervous system.
Fig 1.0 â Proximal portion of the brachial plexus, in the neck. The brachial plexus is a network of nerve fibres that supplies the skin and musculature of the upper limb. It begins in the root of the neck, passes through the axilla, and enters the upper arm. The plexus is formed by the anterior rami (divisions) of the cervical spinal nerves C5, C6, C7 and C8, and the first thoracic spinal nerve, T1. In this article, we shall look at the anatomy of the brachial plexus â its formation and anatomical course through the body.
