Brief Intro to the muscular System  

Talks about the space between a neuron and muscle, and describes with a bit of detail about this relationship. http://www.facebook.com/ArmandoHasudungan PDF: https://docs.google.com/open?id=0B8Ss3-wJfHrpSE5NQThYR051UGc  

The heart's conductions system controls the generation and propagation of electric signals or action potentials causing the hearts muscles to contract and the heart to pump blood.  

Covers the types and characteristics of muscular tissue and microscopic anatomy of skeletal muscle.  

The Muscular System  

This lecture covers the retina, optic nerve, eye muscles, and the orbital bones.  

This is an uncommon ophthalmology finding. With this disorder, the superior oblique muscle spasmically fires, and the eye rotates. Look closely at one of the conjunctival vessels and you can see it move. This is different than rotary nystagmus, as nystagmus are more rhythmic.  

This is an inclusion cyst on the conjunctiva of the eye. These can occur after surgery (often after muscle surgery) and are simply fluid/oil filled cyst from trapped epithelial cells.  

This excerpt comes from a neuro-ophthalmology lecture from Ophthobook.com. Fourth nerve palsies effect the superior oblique muscle (trochlea).  

This is the first 10 minutes of the neuroophthalmology eye lecture from Ophthobook.com. This lecture covers eye-muscle and ocular movement including the direction of action for all the eye muscles and how to document your exam findings.

Ptosis is the lagging of an eyelid. It has 2 distinct etiologies. Sympathetics going to the eye innervate Muller's muscle, a small muscle that elevates the eyelid. The III cranial nerve also innervates a much larger muscle that elevates the eye lid: the levator palpebrae. Thus, disruption of either will cause ptosis. The ptosis from a III nerve palsy is of greater severity than the ptosis due to a lesion of the sympathetic pathway, due to the size of the muscles innervated. As an aside, the parasympathetics run with the III cranial nerve and are usually affected with an abnormal III cranial nerve.  

The rotator cuff (rotor cuff) is a term given to the group of muscles and their tendons that act to stabilize the shoulder. The Rotator Cuff muscles are connected individually to a group of flat tendons, which fuse together and surround the front, the back, and the top of the shoulder joint. The Rotator Cuff ligaments attach bone to bone and provide stability to the shoulder joint bones.
