Tympanic Branch of the Pharyngeal-Basilic Artery [Ramulus Tympanicus (A. Pharyngobasilaris)]

The tympanic branch of the pharyngeal artery [ramulus tympanicus (a. pharyngobasilaris)] is a small artery that arises from the pharyngeal artery (a. pharyngobasilaris) and supplies blood to the middle ear.

The pharyngeal-basic artery is an unpaired vessel formed by the fusion of paired internal carotid arteries. It ascends along the anterior surface of the neck of the pons and divides into two terminal branches - the posterior inferior cerebellar artery and the anterior spinal artery.

Along its length, the pharyngeal-basic artery gives off numerous branches to the brain stem, pons, cerebellum and cranial nerves. One of these branches is the tympanic branch, which goes to the middle ear.

It enters the tympanic cavity through the promontory canal and supplies blood to the mucous membrane of the middle ear, as well as part of the auditory ossicles - the malleus and incus. Thus, the tympanic branch plays an important role in ensuring the normal functioning of the middle ear.

The tympanic vein (vena tympanica) originates from the inner lining of the vena cava at the level of the subclavian cavity and goes to the subcutaneous venous plate of the cervical fascia. It then goes down the lateral surface of the sternocleidomastoid muscle, descends along the outer edge of the long head of the digastric muscle and emerges on the anterior surface of the medial rectus muscle. What supplies the lateral rectus, soleus and gluteus maximus muscles? Below the serratus anterior muscle, a branch branches off from the great saphenous vein of the carotid canal into the common fibula
