The muscles of the neck are a hot topic within anatomy circles. Superiorly - inferior belly of omohyoid muscleĬheck out these learning materials to master the triangles of the neck! Omoclavicular (subclavian/ supraclavicular) triangle Inferiorly - superior belly of omohyoid muscle Inferiorly - middle one-third of clavicleĬontent: external jugular vein, subclavian artery, accessory nerve, cervical plexus, trunks of the brachial plexus Posteriorly - anterior edge of trapezius muscle Posteriorly - anterior border of sternocleidomastoid muscleĪnteriorly - posterior edge of sternocleidomastoid muscle Superiorly - stylohyoid and posterior belly of digastric muscles Laterally - superior belly of omohyoid and anterior border of sternocleidomastoidĪnteroinferiorly - superior belly of omohyoid muscle Medially - posterior belly of digastric muscle Laterally - anterior belly of digastric muscle Laterally - anterior border of sternocleidomastoid muscleĬontent: pharynx, larynx, glands, common carotid, internal carotid and external carotid arteries, internal jugular vein, facial, glossopharyngeal, vagus, hypoglossal nerves It can be subdivided into the occipital triangle and the omoclavicular triangle. Similarly, the posterior triangle is bounded by the posterior border of the sternocleidomastoid muscle, the anterior border of the trapezius muscle and the middle third of the clavicle. This triangle can be further divided into the submandibulartriangle, submentaltriangle, muscular triangle and carotidtriangle. The anterior triangle of the neck is made by the anterior border of the sternocleidomastoid muscle, the inferior border of the mandible and the midline of the neck. There are two main triangles the anterior, and the posterior, triangles of the neck. The neck triangles are actually spaces bordered by the neck muscles. But don’t worry, these triangles are not hard to remember and they are very important for understanding neck anatomy. You may be shocked that we’re mentioning triangles here, as you probably didn’t enroll in anatomy because you love maths. Infrahyoid: Omohyoid, sternohyoid, thyrohyoid, sternothyroid musclesĩ cartilages: Thyroid (1), epiglottic (1), cricoid (1), arytenoid (2), corniculate (2), cuneiform (2) cartilagesĬonsists of left and right lobes connected by a central isthmus, produces thyroxine and triiodothyronineĬonsists of a central body with paired greater and lessor horns Suprahyoid: Stylohyoid, digastric, mylohyoid, geniohyoid muscles Vertebral (1), visceral (1), vascular compartments (2)Īnterior: submandibular, submental, muscular and carotid triangles Key facts about neck anatomy Compartments This page will discuss the anatomy of the neck. So when you hear Bohemian rhapsody, you can turn your head towards that bar and maybe decide to go in and have some fun.

For instance, it supports the position of the head and enables us to turn our head towards stimuli.

Well, luckily, we have necks that attach our heads to our trunks, so joke's on them for saying that.īesides wearing necklaces and spraying perfume, the neck has other functions as well. Regardless of how it happens, the risk of a rotator cuff tear increases as we age and the wear on our bodies accumulates.Every adolescent has heard at least once “don’t forget your head somewhere!” from their parents. A traumatic injury, such as falling onto your arm, can also cause injury. This is why athletes such as baseball pitchers frequently have shoulder issues. Repetitive, overhead motions can wear down the rotator cuff muscles and are thus a common cause of injury. Tear: A less common injury, a rotator cuff tear occurs when a rotator cuff tendon or muscle is torn.Muscle strain, other overuse injuries, and bone spurs are common causes of swelling. Impingement: An impingement occurs when a rotator cuff muscle swells and cramps the space between the arm and shoulder bones, causing pinching.The most common rotator cuff injuries are impingements and tears. She says, “The rotator cuff serves as a sleeve that enables the ball to spin and roll while remaining on the tee.” Physical therapist and founder of WebPT Heidi Jannenga says you should visualize the head of the arm bone as a golf ball, and the area of the shoulder blade as a golf tee. The rotator cuff is a group of four muscles that stabilize the shoulder and allow it to move.

They can be extremely painful, limiting, and slow to heal. As sports fans and athletes alike know, shoulder injuries are serious business.
