What is the anatomy of the neck?
The neck is a complex anatomic region between the head and the body. In the front, the neck extends from the bottom part of the mandible (lower jaw bone) to the bones of the upper chest and shoulders (including the sternum and collar bones). The back of the neck is mostly comprised of muscles, as well as the spine.
What is the lateral surface of neck?
The lateral cervical region has three main borders: the mandible, the internal jugular vein, and the clavicle. As shown in the figure above, the region is inferior to the mandible, anterior to the internal jugular vein, and superior to the clavicle.
What are the superficial structures of the neck?
Where are the superficial muscles of the neck located?
- platysma.
- sternocleidomastoid.
- trapezius.
What tissues are in the neck?
Neck Muscles and Other Soft Tissues
- Levator scapulae. The levator scapulae muscle is attached at the top four cervical vertebrae (C1 to C4) and runs down the side of the neck to attach at the top of the shoulder blade (scapula).
- Sternocleidomastoid (SCM).
- Trapezius.
- Erector spinae.
- Deep cervical flexors.
- Suboccipitals.
What is the bone under your neck called?
The cervical spine has 7 stacked bones called vertebrae, labeled C1 through C7. The top of the cervical spine connects to the skull, and the bottom connects to the upper back at about shoulder level.
Where is C5 and C6 located in the neck?
cervical spine
The C5-C6 spinal motion segment (located in the lower cervical spine just above the C7 vertebra) provides flexibility and support to much of the neck and the head above.
Where is C4 and C5 in the neck?
mid-cervical spine
The C4 and C5 vertebrae are the primary members of the mid-cervical spine. These two members are the most mobile in the mid-neck, and they support most of the forward and backward movements of this section of the neck.
Which muscle forms the anterior surface of the neck?
Muscles in the front of the neck are the suprahyoid and infrahyoid muscles and the anterior vertebral muscles (see the images below). The suprahyoid muscles are the digastrics, stylohyoid, mylohyoid, and geniohyoid. The infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid, and omohyoid.
What are the triangles of the neck?
The three paired triangles are the submandibular (digastric), carotid, and muscular triangles. The unpaired triangle is the submental triangle.
What is surface anatomy called?
Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. In birds this is termed topography. Surface anatomy deals with anatomical features that can be studied by sight, without dissection.
What is surface anatomy with example?
Surface anatomy is the study of the external features of the body. The surface regions of the body have received their names in a variety of ways. Some have everyday names like the palm of the hand, the sole of the foot, and the nape of the neck. Others are named from the organs which lie underneath the skin.
