The posterior triangle is crossed, about 2.5 cm above the clavicle, by the inferior belly of the omohyoid muscle, which divides the space into two triangles: an upper or occipital triangle. a lower or subclavian triangle (or supraclavicular triangle)
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
Level V: Posterior triangle nodes - around the lower half of the spinal accessory nerve and the transverse cervical artery, and includes the supraclavicular nodes. The upper boundary is the apex formed by the convergence of the sternocleidomastoid and trapezius muscles, and inferiorly by the clavicle. The anteromedial border is the posterior ...
Neck. The neck is the part of the body on many vertebrates that connects the head with the torso. The neck supports the weight of the head and protects the nerves that carry sensory and motor information from the brain down to the rest of the body. In addition, the neck is highly flexible and allows the head to turn and flex in all directions.
Subclavian triangle. Side of neck, showing chief surface markings. (Nerves are yellow, arteries are red.) 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 ...
Cephalometric analysis. Cephalometric analysis is the clinical application of cephalometry. It is analysis of the dental and skeletal relationships of a human skull. [1] It is frequently used by dentists, orthodontists, and oral and maxillofacial surgeons as a treatment planning tool. [2] Two of the more popular methods of analysis used in ...
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. Its floor is formed from above downward by the Splenius capitis, Levator scapulæ, and the Scalenus medius and posterior. It is covered by the skin, the superficial and ...
Section of the neck at about the level of the sixth cervical vertebra. Showing the arrangement of the fascia coli. The investing layer of deep cervical fascia is the most superficial part of the deep cervical fascia, and encloses the whole neck. It is considered by some sources to be incomplete [1] or nonexistent. [2]
