Study Notes
Regions of the Neck
- Four main regions: lateral cervical, anterior cervical, SCM (sternocleidomastoid) muscle, trapezius muscle.
- Diagrams can provide a comprehensive view of the neck's anatomical regions.
Muscles in the Neck
- The descending part of the trapezius muscle is significant as a region of the neck.
- Four standard muscles are always found in the lateral cervical region: levator scapulae, splenius capitis, middle scalene, posterior scalene.
- The anterior scalene muscle may occasionally be classified within the lateral cervical region.
Anterior Cervical Region
- All muscles in the anterior cervical region connect to the hyoid bone.
- There are nine identified muscles present in the anterior cervical region.
- Four suprahyoid muscles exist in this region: mylohyoid, geniohyoid, stylohyoid, digastric.
- Five infrahyoid muscles are part of the anterior cervical region: sternohyoid, omohyoid, sternothyroid, thyrohyoid, cricothyroid.
Specific Muscle Functions
- The cricothyroid muscle plays a crucial role in stretching and relaxing the vocal cords, thereby impacting voice modulation.
