Axial Musculature

Skeletal muscles of the body that include those positioning the head and vertebral column, and those moving the rib cage.

Appendicular Musculature

Muscles responsible for stabilizing or moving the appendicular skeleton.

Muscles of the Head and Neck

Group of muscles in the axial musculature including muscles of facial expression, extra-ocular muscles, mastication, tongue, pharynx, and anterior neck.

Muscles of Facial Expression

Muscles that are divided into five groups (mouth, eyes, scalp, nose, neck) and innervated by CN VII.

Extra-ocular Muscles

Muscles controlling eye movement, including medial/lateral rectus and superior/inferior rectus/oblique muscles.

Muscles of Mastication

Muscles responsible for chewing, including the masseter, temporalis, and pterygoids, all innervated by CN V.

Muscles of the Tongue

Includes genioglossus, hyoglossus, palatoglossus, and styloglossus; innervated by CN XII and CN X.

Muscles of the Vertebral Column

Muscles forming three layers: superficial (move neck), intermediate (move vertebral column), and deep (interconnect vertebrae).

Erector Spinae

A group of muscles in the intermediate layer of the intrinsic back muscles including spinalis, longissimus, and iliocostalis.

Flexors of the Knee

Collectively called hamstrings, including biceps femoris, semimembranosus, and semitendinosus.

Extensors of the Knee

Collectively called quadriceps femoris including vastus intermedius, vastus lateralis, vastus medialis, and rectus femoris.

Rotator Cuff

A group of muscles including supraspinatus, infraspinatus, subscapularis, and teres minor involved in shoulder movements.

Diaphragm

Major muscle for breathing, contracting lowers and increasing the thoracic cavity volume for inspiration.

Pelvic Diaphragm

Muscle structure forming the foundation of the pelvic floor, divided into urogenital and anal triangles.

Gluteal Muscles

Muscles that move the thigh, including gluteus maximus, medius, minimus, and tensor fasciae latae.

Intrinsic Muscles of the Foot

Muscles located within the foot responsible for moving the toes, including abductor hallucis, flexor digitorum brevis, and plantar interossei.

Spurt and Shunt Muscles

Type of muscles based on their insertion relative to the joint;

Scalene Muscles

Group of cervical muscles that elevate the ribs during inhalation.

Serratus Anterior

Muscle that protracts the scapula.

Inspiration

Process of inhaling air into the lungs, primarily carried out by diaphragm contraction.

Expiration

Process of exhaling air from the lungs, primarily involves diaphragm relaxation.

Adductor Group

Muscles that move the thigh and include adductor brevis, adductor longus, and adductor magnus.
