What is the bloody triangle in the neck?
This area is often referred to as the “bloody triangle,” because it is a very small area in which blood vessels are hard to locate and coagulate. After the tissue in this area is dissected, it is brought under the nerve and is kept attached to the rest of the tissue as the dissection continues.
How many triangles are in the neck?
The neck is divided into two large triangles (anterior and posterior cervical triangles) by the sternocleidomastoid muscle. It arises from two heads (sternal and clavicular) inferiorly and takes an oblique course superiorly to insert into the mastoid process and lateral aspect of the superior nuchal line.
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 are back neck muscles called?
The fan-shaped trapezius muscles extend from the back of the skull down to the middle of the back, along the spine, and fan over into the shoulders. These muscles give the sides of the neck their shape.
What is the big muscle in your neck called?
Sternocleidomastoid: One of the largest muscles in the neck, helping you move your head, extend your neck and control your temporomandibular joint (in the jaw). It begins just behind your ear and stretches to your collarbone.
Is a radical neck dissection?
Radical neck dissection (RND) refers to the removal of all ipsilateral cervical lymph node groups extending from the inferior border of the mandible superiorly to the clavicle inferiorly and from the lateral border of the sternohyoid muscle, hyoid bone, and contralateral anterior belly of the digastric muscle …
What is a Supraomohyoid neck dissection?
The supraomohyoid neck dissection is a selective cervical node dissection that removes the contents of the submental and submandibular triangles (lymph node level I), the jugulodigastric and jugulo-omohyoid lymph node groups, and the lymph node-bearing tissues located anterior to the cutaneous branches of the cervical …
What is in the supraclavicular triangle?
The subclavian triangle (or supraclavicular triangle, omoclavicular triangle, Ho’s triangle), the smaller division of the posterior triangle, is bounded, above, by the inferior belly of the omohyoideus; below, by the clavicle; its base is formed by the posterior border of the sternocleidomastoideus.
What separates the carotid and submandibular triangle?
To deal with the complex anatomy involved, the cervical region can be organised and divided into what are known as the surgical triangles of the neck. At the most basic division, the neck is divided into the anterior and posterior triangles, which are separated by the sternocleidomastoid muscle.
What are the triangles of the neck?
Triangles of the Neck (Visual mnemonic) Help by adding tags… There are various triangles of the neck, largely divided by the sternocleidomastoid muscle to form anterior and posterior triangles. Some triangles are more ‘important’ that others, and this simplified visual mnemonic hopes to emphasises this.
What is the difference between the anterior and posterior neck triangle?
The anterior triangle of the neck is further subdivided into four smaller triangles, while the posterior triangle is broken up into two smaller triangles. The anterior triangle is the triangular area of the neck found anteriorly to the sternocleidomastoid muscle.
What is the difference between the anterior and muscular triangle?
The muscular (omotracheal) triangle also shares one margin with the anterior triangle – the median line of the neck. However, the muscular triangle begins at the inferior border of the body of the hyoid bone.
What are the anterior and posterior margins of the occipital triangle?
The anterior and posterior margins of the occipital triangle are the same as those of the posterior triangle. However, its base (inferior border) is now formed by the superior margin of the inferior belly of the omohyoid muscle.
