Dissection to show the superficial muscles of the back

This engraving by the anatomist John Bell displays the trapezius and latissimus dorsi muscles of the back. These opposing muscles connect to the vertebral column and contribute to the strength of the upper extremity.

nowealth-noruin:

Drawing (from photo reference) of a superficial dissection of the right shoulder and neck, anterior aspect, illustrating major muscles, nerves, and vessels. The venous plexus above the clavicle is abnormal. Not a terribly refined drawing but mostly I’m just trying to ensure i know my anatomy backwards before I start sticking electrodes in people.

osteocentric:

Drawing of the skeleton of Anna Maria Grumsah who died in Freiburg in 1847. The article accompanying it presents an elaborate and fanciful tale of her as a beautiful woman whose lover left her for another woman and who subsequently descended into dementia and stayed in this position for the last ten years of her life. She was later reported to be dissected at the hospital accompanying the museum at Freiburg and placed on display. Figure used in the British Medical Journal January 17 1857. The story is obviously exaggerated for emotional effect. I have found no other references to this story or skeleton.

Vessels and nerves of the choroid and iris

This cutaway diagram clearly shows the position and relation of the sclera to the inner workings of the eyeball.

Comprising the posterior five-sixths of the connective tissue surrounding the eyeball, the sclera is contiguous with the cornea (the anterior one-sixth of the connective tissue) and the dura mater surrounding the optic nerve. Yes, that’s the same “dura mater” connective tissue that’s found surrounding the brain - in mammals, the eyes are simply outgrowths of the brain itself, not independently developed sensory organs (as they are in, say, cephalopods).

Also known as “the whites of the eye”, the sclera is comprised primarily of collagen and elastic tissue, and is a fairly durable and tough outer casing for the inner structures of the eyeball. Directly interior to the sclera is the choroid, which provides much of the structural definition and vasculature of the eyeball, but is very delicate on its own.

Humans are fairly unique among mammals in that the whites of our eyes are always showing. The small size of our irises and the contrast against the sclera allows us to clearly communicate nonverbal (and often subconscious) cues to one another using only our eyes.
