What does Omo mean in Omohyoid?

Medical Definition of omohyoid : of or relating to the shoulder and the hyoid bone.

The omohyoid muscle is a long, thin muscle consisting of superior and inferior bellies and an intermediate tendon, which runs obliquely in the lateral cervical region. The omohyoid is important in neck dissections because it is the surgical landmark for level III and IV lymph node metastases.

Origin. The thyrohyoid is a paired broad, short muscle that originates along the oblique line on the lamina of the thyroid cartilage.

The shoulder (sometimes including the upper arm). [G. ōmos, shoulder]

(anatomy) Of the shoulder or scapula.

The hyoidal attachments of the sternohyoid and omohyoid muscles are supplied by the hyoid artery, as is the whole thyrohyoid muscle. The hyoid artery arises either directly from the STA or secondarily from its superior laryngeal branch.

The omohyoid, sternohyoid, and thyrohyoid act to depress the hyoid bone. The thyrohyoid elevates the larynx whereas the sternothyroid depress the larynx.

This group of muscles contains four main muscles: the omohyoid muscle, the sternohyoid muscle, the sternothyroid muscle, and the thyrohyoid muscle. The primary function of this group of muscles is to depress the hyoid bone during speech and swallowing.

Place palpating fingers along the muscle fiber direction just inferior to the hyoid bone. Ask the patient to swallow. Inferior belly. Place palpating fingers along the muscle fiber direction just lateral to SCM and superior to the clavicle (note scalene fiber direction is more vertical).

The levator scapulae muscle connects to the transverse processes of the top four cervical vertebrae (C1 to C4) and runs down the side of the neck where it eventually connects with the scapula (shoulder blade).

It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint. In total, 17 different muscles attach to the scapula, which makes it difficult to fracture.

Innervation. The geniohyoid muscles are innervated by a branch of the ventral ramus of C1 from the cervical plexus which courses with the hypoglossal nerve in to the floor of the mouth.

Anatomical terms of muscle The thyrohyoid muscle is a small skeletal muscle on the neck. It originates from the lamina of the thyroid cartilage, and inserts into the greater cornu of the hyoid bone.

The genioglossus muscle is a fan-shaped muscle that is involved in forming most of the tongue mass. It emerges from the superior mental spines and inserts on the hyoid bone as well as the inferior portion of the tongue. [1] The genioglossus muscle divides into four main parts: Anterior.

Prefix. (anatomy) Of or pertaining to the shoulder and scapula.

-oma. A suffix meaning “tumor” or “cancer,” as in carcinoma.

[for´ahrm] the part of the upper limb between the elbow and wrist; called also antebrachium.

Omo. Definition: A man or a buddy.

The omohyoid muscle is an infrahyoid muscle of the neck that is innervated by the ansa cervicalis of the cervical plexus receiving fibers from the ventral rami of C1–C3 spinal nerves.

The superior thyroid artery is a major blood vessel in your circulatory system that supplies oxygenated blood to the thyroid gland and larynx (voice box). The thyroid is in the front of your neck and produces an array of hormones vital to many bodily functions.

The anterior belly of the digastric receives innervation from the mylohyoid nerve. The mylohyoid nerve is a branch of the inferior alveolar nerve, which arises from the mandibular branch of the trigeminal nerve.

The mylohyoid mainly functions to elevate the hyoid bone, elevate the oral cavity, and depress the mandible.

The ansa cervicalis (or ansa hypoglossi) is the union of the C1, C2, and C3 nerves from the cervical plexus, which provides innervation to the infrahyoid muscles (Figure 31.2).

Functions of the stylohyoid muscle include: elevation of the hyoid bone superiorly and posteriorly during swallowing. depression of the mandible.

The four infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles. Excluding the sternothyroid, the infrahyoid muscles either originate from or insert on to the hyoid bone.

Nerve supply derives from the second pharyngeal arches (facial nerve). It is the stylohyoid branch of the facial nerve (cranial nerve VII) that innervates this muscle. Sometimes, the nerve towards the posterior belly of the digastric (branch of the facial nerve) also gives a branch to the stylohyoid muscle.

Sternocleidomastoid (scm) muscle pain typically brings complaints of dizziness or sudden hearing loss, headache or jaw pain, even when everything appears to be normal. If this is the case it might be time to consider a muscular or mechanical reason for the symptoms.

Origin and insertion. Anterior belly of digastric muscle. Venter anterior musculi digastrici. Synonyms: Mandibular belly of digastric muscle, Venter mandibularis musculi digastrici. The digastric muscle is comprised of two parts; anterior and posterior bellies, joined by an intermediate tendon.

Each scapula has 17 muscles attached to it: 1. Posteriorly, from superficial to deep: trapezius, rhomboid major, rhomboid minor, supraspinatus, infraspinatus, levator scapulae, teres minor, teres major, latissimus dorsi, serratus anterior, and subscapularis. 2.

The inferior angle of the scapula is where the vertebral (medial) and axillary (lateral) borders intersect.

The hyoglossus muscle is one of the four intrinsic muscles of the tongue. It is a quadrilateral muscle that originates along the whole length of the hyoid bone and inserts into the side of the tongue. The hyoglossus acts to both depress and retract the tongue.

Extrinsic muscles of the tongue. Left side. Branches of the lingual artery.

The soft patty of flesh we call the tongue is not just one muscle, it’s a conglomeration of eight separate muscles. Unlike other muscles, such as the bicep, tongue muscles don’t develop around a supporting bone.
