Hilton's law, espoused by John Hilton in a series of medical lectures given in 1860–1862, [1] is the observation that in the study of anatomy, the nerve supplying the muscles extending directly across and acting at a given joint not only supplies the muscle, but also innervates the joint and the skin overlying the muscle.
The oculomotor nerve includes axons of type GSE, general somatic efferent, which innervate skeletal muscle of the levator palpebrae superioris, superior rectus, medial rectus, inferior rectus, and inferior oblique muscles. (Innervates all the extrinsic muscles except superior oblique and lateral rectus.)
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
Muscle contraction is stimulated by the motor neuron sending a message to the muscles from the somatic nervous system. Depolarization of the motor neuron results in neurotransmitters being released from the nerve terminal. The space between the nerve terminal and the muscle cell is called the neuromuscular junction.
After nerve trauma around the eye, a combination of any two of these three cranial nerves have been shown to be involved with extra-ocular synkinesis. Moreover, while the abducens and the trochlear nerve each innervate one specific muscle, the oculomotor nerve has many functions including eyelid retraction and pupil constriction.
tibial nerve; common fibular nerve (also known as the common peroneal nerve) [3] popliteal vein; popliteal artery, a continuation of the femoral artery; small saphenous vein (termination) [3] Popliteal lymph nodes and vessels [3] It is of note that the common fibular nerve also begins at the superior angle of the popliteal fossa.

The main function of the Edinger-Westphal nucleus is to send axons in the oculomotor nerve to control the ciliary ganglion which in turn, sends its axons in the short ciliary nerve to control the iris and the ciliary muscle of the eye. The oculomotor neurons functions to send its axons in the oculomotor nerve, to control the medial rectus, and ...
The oblique popliteal ligament is formed as a lateral expansion of the tendon of the semimembranosus muscle [2] and represents one of the muscle's five insertions. [citation needed] The ligament blends with the posterior portion of the knee joint capsule. [2] It exhibits a large opening through which nerves and vessels pass. [3]
