What are the boundaries of submental triangle?

What are the boundaries of submental triangle?

Borders. The submental triangle, also referred to as the suprahyoid triangle, is an unpaired suprahyoid area lying inferior to the chin. It is limited by the body of the hyoid bone inferiorly, laterally by the right and left anterior bellies of the digastric muscles.

What are the boundaries of the triangles of the neck?

Laterally, the anterior triangle is bounded by the anterior border of the sternocleidomastoid muscle. Its superior border is the inferior border of the mandible. Medially, the boundary is the midline of the neck. The anterior triangle can further subdivide into four sub-triangles.

What is the submental region of the neck?

The submental space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space located between the mylohyoid muscle superiorly, the platysma muscle inferiorly, under the chin in the midline.

What are the borders of the anterior triangle of the neck?

The anterior cervical triangle is bounded by the midline of the neck, the anterior border of the sternocleidomastoid muscle (SCM), and the inferior border of the mandible [3]. This triangle is typically subdivided into three paired and one unpaired triangle.

What are the borders of the submandibular triangle?

The submandibular triangle, also known as the digastric triangle, is bounded anteriorly by the anterior belly of the digastric muscle, posteriorly by the posterior belly of the digastric muscle, superiorly by the mandible, and inferiorly by the mylohyoid and hypoglossus muscles.

What are the borders of the occipital triangle?

The occipital triangle, the larger division of the posterior triangle, is bounded, in front, by the Sternocleidomastoideus; behind, by the Trapezius; below, by the Omohyoideus.

Where is the submental area?

The submental space is a deep compartment of the head and neck that lies in the midline submental triangle below the chin, medially to the submandibular spaces with which it freely communicates. Some authors include the submental space as a component of the submandibular or submaxillary space 1,2.

What are the boundaries of the submandibular region?

The boundaries of the submandibular triangle are:

• Superiorly – body of the mandible.
• Anteriorly – anterior belly of the digastric muscle.
• Posteriorly – posterior belly of the digastric muscle.

What separates carotid triangle from submandibular triangle?

At the most basic division, the neck is divided into the anterior and posterior triangles, which are separated by the sternocleidomastoid muscle. Focusing specifically on the anterior triangle, it can be divided into four smaller triangles, which are the: carotid triangle. submental triangle. muscular (visceral) …

What three landmarks create the borders of the necks anterior triangle?

The anterior triangle is the triangular area of the neck found anteriorly to the sternocleidomastoid muscle. It is formed by the anterior border of sternocleidomastoid laterally, the median line of the neck medially and by the inferior border of the mandible superiorly.

Where is the submandibular triangle?

The submandibular triangle, also known as digastric triangle, is located superior to the hyoid bone. It is bordered: superiorly by the inferior border of the mandible and the mastoid process, posteriorly by the posterior belly of the digastric and stylohyoid muscles, and.

Where is the submaxillary triangle located?

The submandibular triangle (or submaxillary or digastric triangle) corresponds to the region of the neck immediately beneath the body of the mandible. Side of neck, showing chief surface markings.

What is digastric triangle?

Where is the submental area located?

anterior triangle of the neck
Description. The submental space is located between the mylohyoid muscle superiorly, the platysma muscle inferiorly, under the chin in the midline. The space coincides with the anatomic region termed the submental triangle, part of the anterior triangle of the neck.

What is a submental area?

Where are the submental nodes located?

neck
Submental lymph nodes are small lymph nodes found below the chin in the submental triangle of the neck, lying between the two anterior bellies of the digastric muscle. They belong to the submental group of lymph nodes of the head, and include the anterior, middle and posterior submental lymph nodes.

How many submental lymph nodes are there?

The submandibular lymph nodes (submaxillary glands in older texts), three to six in number, are lymph nodes beneath the body of the mandible in the submandibular triangle, and rest on the superficial surface of the submandibular gland.

Where are the submental lymph nodes located?

Is submental lymph node palpable?

Occasionally nodes will remain enlarged and palpable after an infection. This is a relatively common occurrence especially within the submandibular group of lymph nodes. When examined, these nodes should be small (less than 1 cm), non-tender and mobile.
