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 boundaries of the carotid triangle?
The carotid triangle is bordered by the posterior belly of the digastric muscle, the superior belly of the omohyoid muscle, and the anterior border of the SCM. The floor and medial wall of this triangle is formed by the hyoglossus, thyrohyoid, and inferior and middle pharyngeal constrictor muscles.
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 is the inferior border of the submandibular space?
inferiorly to the lateral pharyngeal space.
What is the lateral boundary of the submental triangle?
Boundaries. It is limited to: Lateral (away from the midline), formed by the anterior belly of the digastricus. Medial (towards the midline), formed by the midline of the neck between the mandible and the hyoid bone.
What is the Anterosuperior boundary of the carotid triangle?
It is bounded: Posteriorly by the anterior border of the Sternocleidomastoid; Anteroinferiorly, by the superior belly of the Omohyoid muscle.
What is the occipital triangle?
The occipital 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).
Where is the submandibular region located?
The submandibular gland is in the posterior portion of the submandibular triangle, which is formed by the body of the mandible superiorly, the anterior belly of the digastric muscle medially, and the posterior belly of the digastric muscle inferiorly and laterally.
Where is submandibular located?
About the size of a walnut, the submandibular glands are located below the jaw. The saliva produced in these glands is secreted into the mouth from under the tongue. Like the parotid glands, the submandibular glands have two parts called the superficial lobe and the deep lobe.
What are the borders of submandibular space?
The submandibular space is bounded anteriorly and laterally by the mandible, medially by the anterior belly of the digastric muscles, superiorly by the mylohyoid muscle and inferiorly by the hyoid bone (Figs.
Which triangles are placed within lateral region of neck?
This space is subdivided into two large triangles by sternocleidomastoid, which passes obliquely across the neck, from the sternum and clavicle below, to the mastoid process and occipital bone above.
What is the side of the neck called?
The quadrangular area is on the side of the neck and is bounded superiorly by the lower border of the body of the mandible and the mastoid process, inferiorly by the clavicle, anteriorly by a midline in front of the neck, and posteriorly by the trapezius muscle.
Where does the carotid canal start and end?
The carotid canal is initially directed superiorly, then turns anteromedially to reach up to the petrous apex. It runs approximately 2 cm within the petrous bone and opens into the middle cranial fossa superior to the foramen lacerum.
What is the function of carotid canal?
The carotid canal allows the internal carotid artery to pass into the cranium, as well as the carotid plexus traveling on the artery. The carotid plexus contains sympathetics to the head from the superior cervical ganglion.
What is Pirogov surgery?
But for Pirogov surgery was much more than just finding a path to a particular structure, be it a nerve, vein, artery or an internal organ. Surgery must be based on an intimate knowledge of anatomy and the topography of the relevant structures as well as the changes caused by pathological processes.
What is Pirogov’s contribution to forensic pathology?
Nikolay Pirogov was interested not only in anatomy and its application to surgery, but also in its value to forensic pathology (Pirogov, 1849a, 1957 ).
What is the difference between Pirogov angle and aponeurosis?
The Pirogov angle (or venous angle) lies at the junction of the internal jugular and the subclavian veins; and the Pirogov aponeurosis, also known as the biceps aponeurosis, is a broad aponeurosis of the biceps muscle in the cubital fossa of the elbow separating superficial from deep structures in much of the fossa.
