The labyrinthine artery supplies blood to the inner ear. [1] [3] ... This can cause loss of hearing and balance on the affected side. [3] History
The head and neck are emptied of blood by the subclavian vein and jugular vein. Right side of neck dissection showing the brachiocephalic, right common carotid artery and its branches The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery .
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates , the inner ear is mainly responsible for sound detection and balance. [ 1 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
Each vessel passes obliquely upward, from behind the sternoclavicular joint to the level of the upper border of the thyroid cartilage, where it divides. At the lower neck, the two common carotid arteries are separated from each other by a very narrow interval which contains the trachea; but at the upper part, the thyroid gland , the larynx and ...
Gas bubble formation in blood vessels causes obstruction and inflammation, and platelet aggregation may occur. [11] In more solid tissues there may be mechanical damage, and the presence of mobile bubbles in the fluids of the inner ear may cause abnormal stimuli. The pathogenesis remains elusive, [13] and may have more than one mechanism ...
Structures homologous to the stapedial artery in humans and other primates can be derived from a primitive, hypothetical pattern similar to that found in primitive rodents: the stapedial artery enters the middle cranial fossa and splits into the anterior and inferior divisions of the superior ramus and the inferior ramus.
Segments of the internal carotid artery, delineated on an MRA of the head.. The internal carotid artery is a terminal branch of the common carotid artery; it arises around the level of the fourth cervical vertebra when the common carotid bifurcates into this artery and its more superficial counterpart, the external carotid artery.
The upper branch accompanies the accessory nerve to the sternocleidomastoid, and the lower branch arises near the origin of the occipital artery before entering the sternocleidomastoid muscle. Occasionally, this branch arises directly from the external carotid artery. Auricular branch: supplies the back of the ear.
