Muscle, Skeletal

Definition: Striated muscles having fibers connected at either or both extremities with the bony framework of the body. These are found in appendicular and axial muscles. (From Stedman, 25th ed)
Notes: /growth: coord with MUSCLE DEVELOPMENT; /embryol: coord with MUSCLE DEVELOPMENT if pertinent
Also Called: Anterior Tibial Muscle,Gastrocnemius Muscle,Muscle, Striated,Plantaris Muscle,Soleus Muscle
Previously Indexed: Muscles (1966-1994)

Muscle, Skeletal Categories.
Abdominal Muscles - Muscles forming the ABDOMINAL WALL including RECTUS ABDOMINIS, external and internal oblique muscles, transversus abdominis, and quadratus abdominis. (from Stedman, 25th ed)
Facial Muscles - Muscles of facial expression or mimetic muscles that include the numerous muscles supplied by the facial nerve that are attached to and move the skin of the face. (From Stedman, 25th ed)
Laryngeal Muscles - The intrinsic muscles of the larynx are the aryepiglottic(us), arytenoid(eus), cricoarytenoid(eus), cricothyroid(eus), thyroarytenoid(eus), thyroepiglottic(us) and vocal(is).
Masticatory Muscles - Muscles arising in the zygomatic arch that close the jaw. Their nerve supply is masseteric from the mandibular division of the trigeminal nerve. (From Stedman, 25th ed)
Neck Muscles - The neck muscles consist of the platysma, splenius cervicis, sternocleidomastoid(eus), longus colli, the anterior, medius, and posterior scalenes, digastric(us), stylohyoid(eus), mylohyoid(eus), geniohyoid(eus), sternohyoid(eus), omohyoid(eus), sternothyroid(eus), and thyrohyoid(eus).
Oculomotor Muscles - The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.
Palatal Muscles - The muscles of the palate are the glossopalatine, palatoglossus, levator palati(ni), musculus uvulae, palatopharyngeus, and tensor palati(ni).
Pectoralis Muscles - The pectoralis major and pectoralis minor muscles that make up the upper and fore part of the chest in front of the AXILLA.
Pharyngeal Muscles - The muscles of the pharynx are the inferior, middle and superior constrictors, salpingopharyngeus, and stylopharyngeus.
Psoas Muscles - A powerful flexor of the thigh at the hip joint (psoas major) and a weak flexor of the trunk and lumbar spinal column (psoas minor). Psoas is derived from the Greek "psoa", the plural meaning "muscles of the loin". It is a common site of infection manifesting as abscess (PSOAS ABSCESS). The psoas muscles and their fibers are also used frequently in experiments in muscle physiology.
Respiratory Muscles - These include the muscles of the DIAPHRAGM and the INTERCOSTAL MUSCLES.
Rotator Cuff - The musculotendinous sheath formed by the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. These help stabilize the head of the HUMERUS in the glenoid fossa and allow for rotation of the SHOULDER JOINT about its longitudinal axis.
Sarcoplasmic Reticulum - A network of tubules and sacs in the cytoplasm of skeletal muscles that assist with muscle contraction and relaxation by releasing and storing calcium ions.
Stapedius - The stapedius muscle arises from the wall of the middle ear and is inserted into the neck of the stapes. Its action is to pull the head of the stapes backward.
Tensor Tympani - Tensor muscle of the tympanic membrane that draws the handle of the malleus medialward and tenses the tympanic membrane. (Stedman, 25th ed)
