Sleepy Triangle

The carotid triangle (trigonum caroticum, pna, jna; fossa carotica, bna; trigonum omohyoideum) is an anatomical area on the anterior surface of the neck. It is located on the sides of the larynx and is bounded below by the hyoid bone, on the side by the anterior edge of the sternocleidomastoid muscle, and above by the lower jaw.

The carotid triangle contains the common carotid artery, internal jugular vein and vagus nerve. These structures are separated from the surface by the fascia of the middle layer of the neck. The carotid triangle has important clinical significance, since it is here that the pulsation of the carotid artery can be felt.

The boundaries of the sleepy triangle are:

  1. below - transverse line at the level of the hyoid bone;

  2. above - the lower edge of the body of the lower jaw;

  3. on the side - the anterior edge of the sternocleidomastoid muscle.

Overall, the carotid triangle is an important anatomical region containing vital neurovascular structures of the neck.



The carotid triangle is a structure in the human body that plays an important role in regulating blood flow and breathing. It consists of three parts: the carotid fossa, the carotid sinus and the great carotid artery. This area is also called the carotid fossa or hypoglossal fossa.

The carotid triangle is located in the human neck between the neck and the thoracic spine. It is located at the junction of the two bones that form this section of the neck: the C1 and C2 vertebrae and the collarbone. Due to this location, this triangle has become the focus of many medical studies, especially regarding sleep apnea and related diseases.

Complications of the carotid triangular region greatly impact a person's health and well-being. Some of these include drop in blood oxygen levels, heart attack, arrhythmia, stroke, respiratory failure and stroke.

The causes of hypertension can be associated with both external factors and the genetic characteristics of the body. As a result, it can lead to deterioration of health and the appearance of additional diseases. In addition, hypertension can affect the functioning of the cardiovascular system, increasing the risk of myocardial infarction and stroke.

Symptoms of hypertension include headache, high blood pressure, dizziness, weakness, insomnia, memory loss and problems with the heart and kidneys. If you suspect hypertension, you should consult a doctor to conduct the necessary examinations and prescribe the correct treatment.
