Study Notes
Trapezius Muscle
- The trapezius muscle is a large, superficial muscle located in the upper back and neck region.
- It extends from the occipital bone (back of the skull) and the superior portion of the thoracic vertebrae down to the scapulae (shoulder blades).
- It is shaped like a trapezoid, hence its name.
Erector Spinae
- The erector spinae muscles are located in the back, along the vertebral column.
Diaphragm
- The diaphragm is a dome-shaped muscle that separates the chest from the abdomen.
Levator Scapulae
- This muscle is located in the upper back and neck area.
- It helps elevate the scapula (shoulder blade).
Sternocleidomastoid
- This muscle is located on the side of the neck, extending from the sternum (breastbone) to the mastoid process (behind the ear).
Orbicularis Oculi
- A circular muscle surrounding the eye socket.
- Responsible for closing the eyelids.
Orbicularis Oris
- A ring-like muscle surrounding the mouth.
- Responsible for closing the lips and puckering the mouth.
Depressor Labii Inferioris
- This muscle is located on the lower lip.
- Responsible for pulling the lower lip down.
