Middle temporal artery

Middle Temporal Artery

The Middle Temporal Artery is a significant artery located in the human body. It is a branch of the Superficial Temporal Artery, which is itself a major branch of the External Carotid Artery. The Middle Temporal Artery supplies blood to the Temporalis muscle, a broad, fan-shaped muscle on each side of the head that covers much of the Temporal bone.

Etymology

The term "Middle Temporal Artery" is derived from its location and function. The word "middle" refers to its position between the superficial and deep layers of the Temporalis muscle. "Temporal" is derived from the Latin word "tempus," which means "time." This is because the Temporalis muscle, which the artery supplies, is located near the temples, a region of the head that often shows the first signs of aging, or the passage of time.

Anatomy

The Middle Temporal Artery arises from the Superficial Temporal Artery in the substance of the Parotid gland, a major salivary gland located in front of the ear. It then ascends to the temporal region, where it ramifies beneath the Fascia, supplying the Temporalis muscle and anastomosing with the Deep Temporal Arteries.

Clinical Significance

The Middle Temporal Artery, like other arteries, can be affected by various medical conditions. For instance, Atherosclerosis, a disease in which plaque builds up inside arteries, can lead to the narrowing of the Middle Temporal Artery, reducing blood flow to the Temporalis muscle. This can cause symptoms such as headache and muscle weakness.
