  2. Cervical spinal nerve 5 - Wikipedia

    en.wikipedia.org/wiki/Cervical_spinal_nerve_5

    The cervical spinal nerve 5 (C5) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 5 (C5). It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the ...

  3. Complement component 5 - Wikipedia

    en.wikipedia.org/wiki/Complement_component_5

    Complement component 5 is a protein that in humans is encoded by the C5 gene. [5] Complement component 5 is involved in the complement system. It is cleaved into C5a and C5b: C5a plays an important role in chemotaxis. [6] C5b forms the first part of the complement membrane attack complex. Deficiency is thought to cause Leiner's disease.

  4. Spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Spinal_nerve

    A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. [1] [2] These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. [1]

  5. Upper trunk - Wikipedia

    en.wikipedia.org/wiki/Upper_trunk

    It is formed by joining of the ventral rami of the fifth (C5) and sixth (C6) cervical nerves. The upper trunk divides into an anterior and posterior division. The branches of the upper trunk from proximal to distal are: subclavian nerve (C5-C6) suprascapular nerve (C5-C6) anterior division of upper trunk (C5-C6, forms part of lateral cord)

  6. Phrenic nerve - Wikipedia

    en.wikipedia.org/wiki/Phrenic_nerve

    As with most nerves in the neck, multiple anatomic variants have been described. Notably, there may be variability in the course of the phrenic nerve in the retro-clavicular region such that the nerve courses anterior to the subclavian vein, rather than its typical position posterior to the vein (between the subclavian vein and artery). [3]

  7. Cervical vertebrae - Wikipedia

    en.wikipedia.org/wiki/Cervical_vertebrae

    The most distinctive characteristic of this bone is the strong odontoid process (dens) that rises perpendicularly from the upper surface of the body and articulates with C1. The body is deeper in front than behind, and prolonged downward anteriorly so as to overlap the upper and front part of the third vertebra.

  8. The Clitoris And The Body - The Huffington Post

    projects.huffingtonpost.com/projects/cliteracy/...

    From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.

  9. Brachial plexus - Wikipedia

    en.wikipedia.org/wiki/Brachial_plexus

    The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
