Scalene Muscles are three muscle groups located in the deep layer of the neck that function in movement of the upper ribs, lateral flexion of the neck, and respiratory support. They are classified as anterior (scalenus anterior), middle (scalenus medius), and posterior (scalenus posterior). A fourth variant, scalenus minimus, may occasionally be present.Anatomical StructureMorphology and Attachment PointsThe scalene muscles consist of three primary muscles located laterally in the neck, originat

Giraffe weevil (Trachelophorus giraffa) is a beetle species endemic to Madagascar, named for the elongated neck that is particularly prominent in males. This extended neck provides additional leverage during competition among males for mating rights and when rolling leaves to construct nests.Physical CharacteristicsThe most striking feature of the giraffe weevil is the elongated neck, which is significantly more pronounced in males than in females. Male necks are approximately two to three times

The Omohyoid Muscle is a muscle located in the anterior neck that depresses the hyoid bone. Composed of two bellies (superior and inferior), this muscle serves as an anatomical landmark for defining the boundaries of the neck triangles.AnatomyMorphology and Connection PointsThe Omohyoid Muscle is a thin, long, and obliquely oriented muscle located between the infrahyoid muscles. It consists of two distinct parts: the superior and inferior belly. The inferior belly originates from the superior bo

The Levator Scapulae Muscle is a muscle located in the posterolateral region of the neck and is responsible for elevating the scapula. It lies beneath the trapezius muscle and plays an important role in shoulder stabilization.AnatomyMorphology and Connection PointsThe Levator Scapulae Muscle is a long, narrow muscle located in the posterolateral region of the neck. It helps elevate the scapula. It is located deep within the neck, beneath the trapezius and sternocleidomastoid muscles. This anatom

The Sternocleidomastoid Muscle is one of the most prominent and powerful muscles of the neck. It functions in head rotation, neck flexion, and assists in respiration. It is innervated by the accessory nerve (CN XI) and serves as a key anatomical landmark in defining the boundaries of the neck.Anatomical StructureMorphology and Attachment PointsThe sternocleidomastoid muscle is a strong, superficial muscle located in the anterolateral region of the neck. It has two heads: the sternal head origina

Platysma muscle is a thin, broad muscle located in the superficial layer of the neck. It plays a role in facial expressions, mandibular movements, and tensioning of the neck skin. It is innervated by the facial nerve (CN VII) and is an important structure in aesthetic surgery.Anatomical StructureMorphology and Attachment PointsThe platysma muscle is a thin, broad superficial muscle that originates from the fascia overlying the pectoralis major and deltoid muscles and extends upward to the upper
