The three paired triangles are the submandibular (digastric), carotid, and muscular triangles. The unpaired triangle is the submental triangle.

Are there muscular triangles in the neck?

The inferior carotid triangle (or muscular triangle), is bounded, in front, by the median line of the neck from the hyoid bone to the sternum; behind, by the anterior margin of the sternocleidomastoid; above, by the superior belly of the omohyoid. Side of neck, showing chief surface markings.

What is posterior triangle of neck?

The posterior triangle has the following boundaries: Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle.

What is carotid triangle?

The carotid triangle is one of the paired triangles in the anterior triangle of the neck. The triangles of the neck are surgically focused, first described from early dissection-based anatomical studies which predated cross-sectional anatomical description based on imaging (see deep spaces of the neck).

What is digastric 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 is in the occipital triangle?

Occipital triangle (omotrapezoid triangle)

muscular boundaries: anteriorly - by the posterior margin of the sternocleidomastoid muscle. posteriorly - by the trapezius muscle. inferiorly - by the inferior belly of the omohyoid muscle.

Where is Pirogov's triangle located?

The Pirogov triangle (also Piragoff's triangle) is an area in the human neck formed by the intermediate tendon of the digastric muscle, the posterior border of the mylohyoid muscle, and the hypoglossal nerve.

What is in the submental triangle?

The submental triangle harbors the submental lymph nodes that drain the mental region, the tip of the tongue, inferior lip, and incisor teeth. Also, the mylohyoid nerve and veins that drain into the anterior jugular vein traverse this region [2].

What is inside submandibular triangle?

As previously mentioned, the roof of the submandibular triangle i.e. the first plane encountered surgically comprises of the skin and the superficial fascia. These enclose the platysma muscle and the subcutaneous fat. Also enclosed are the cervical and mandibular branches of the facial nerve (cranial nerve VII).

Where is the hyoid?

The hyoid bone (hyoid) is a small U-shaped (horseshoe-shaped) solitary bone, situated in the midline of the neck anteriorly at the base of the mandible and posteriorly at the fourth cervical vertebra. Its anatomical position is just superior to the thyroid cartilage.

Where is the ANSA Cervicalis?

The ansa cervicalis is a neural loop in the neck formed by connecting the superior root from the cervical spinal nerves (C1–2) and the inferior root descending from C2–C3. It has various anatomical variations and can be an important acknowledgment in specific operations of the neck region.

What forms the carotid triangle?

It is formed by the middle cervical fascia where it encompasses the vagus nerve (CN X) as well as the internal jugular vein, the common carotid artery, and deep cervical lymph nodes.

What is supraclavicular triangle?

The supraclavicular triangle is one of the paired triangles in the posterior triangle of the neck. The triangles of the neck are surgically focused, first described from early dissection-based anatomical studies which predated cross-sectional anatomical description based on imaging (see deep spaces of the neck).

What is the triangle of life body parts?

The tripartite or threefold nature of this triangle consists of physical fitness,^1,2 nutrition, and rest. Physical fitness, in the form of five 30-minute sessions of vigorous exercise each week, strengthens our heart, lungs, and every muscle fiber in our body.

What do you have 3 of in your body?

3 muscles that comprise the triceps surae - grastrocnemius m. soleus m. plantaris m. 3 muscles in the deep posterior compartment - tibialis posterioris m.

What are the 3 parts of the body?

The human body consists of a bony skeleton and muscles. The three main parts of the body are: the head, the trunk and the limbs (extremities).

Which of the following muscles divides the neck into two triangles?

The sternocleidomastoid muscle divides the neck region into posterior and anterior triangles.

What is the Wharton's duct?

Wharton's duct is a thin tube, about 5 cm in length, and an essential carrier of your saliva. Each submandibular duct begins at the right and left sides of the mouth. The submandibular duct openings are underneath the tongue. These openings that empty into the oral cavity are also known as sublingual caruncles.

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.

Why is it called submental triangle?

The submental triangle defines a sub-region of the anterior cervical region (anterior triangle of the neck). It is one of four smaller triangles within the anterior triangle of the neck and contains some important vascular structures.
