The suprasternal notch is a visible dip in between the neck, between the clavicles, and above the manubrium of the sternum. It is at the level of the T2 and T3 vertebrae. [1] The trachea lies just behind it, rising about 5 cm above it in adults.
The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium. This notch can be felt between the two clavicles. On either side of this notch are the right and left clavicular notches. [1] The manubrium joins with the body of the sternum, the clavicles and the cartilages of the first 1.5 pairs of ...
Anterior boundary. Midline of the neck from chin to the jugular notch. Posterior boundary. The anterior margin of sternocleidomastoid. Superior boundary (base) The lower border of the body of the mandible, and a line extending from the angle of the mandible to the mastoid process. Investing fascia covers the roof of the triangle while visceral ...
552. FMA. 52735. Anatomical terms of bone. [edit on Wikidata] The occipital bone (/ ˌɒkˈsɪpɪtəl /) is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull). It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone overlies the occipital lobes of the cerebrum.
Anatomical terms of muscle. [edit on Wikidata] The sternocleidomastoid muscle is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. [3] The sternocleidomastoid is innervated by the accessory nerve. [3]
Outer surface. [clarification needed] The petrous part of the temporal bone is pyramid-shaped and is wedged in at the base of the skull between the sphenoid and occipital bones. Directed medially, forward, and a little upward, it presents a base, an apex, three surfaces, and three angles, and houses in its interior the components of the inner ear.
The clivus (/ ˈklaɪvəs /, [1] Latin for "slope") or Blumenbach clivus is a part of the occipital bone at the base of the skull. [2] It is a shallow depression behind the dorsum sellae of the sphenoid bone. It slopes gradually to the anterior part of the basilar occipital bone at its junction with the sphenoid bone.
The transpyloric plane, also known as Addison's plane, is an imaginary horizontal plane, located halfway between the suprasternal notch of the manubrium and the upper border of the symphysis pubis at the level of the first lumbar vertebrae, L1. It lies roughly a hand's breadth beneath the xiphisternum [1] or midway between the xiphisternum and ...
