origin of inferior pharyngeal constrictor muscle

Origin of inferior pharyngeal constrictor muscle skin#

The frontalis muscle is also used in reconstruction for example frontalis myofascial flaps for cranialization of the frontal sinus 3. Inserts posteriorly into the pharyngeal raphe. The frontalis muscle has clinical significance in relation to facial aesthetics and pathology related to defects of soft tissue and imbalances of motor control.

Although the UES is often described as a 2- to 4-cm zone of high pressure. It inserts onto the pharyngeal raphe and constricts sequentially in coordination with the SCPM and MCPM during deglutition to propel the bolus towards the esophagus. This muscle forms the majority of the upper esophageal sphincter (UES). The inferior constrictor pharyngeal muscle (ICPM) originates from the cricoid and thyroid cartilages and crosses the cricothyroid muscle. Its most caudal portion is commonly referred to as the cricopharyngeus (CP) muscle.

action: pulling of the scalp anteriorly, wrinkling of the forehead skin, and elevation of the eyebrows The inferior pharyngeal constrictor (IPC) is the thickest and best developed of the three pharyngeal constrictors.

innervation: temporal branches of the facial nerve.

arterial supply: frontal branch of the superficial temporal artery laterally and the supratrochlear and supraorbital arteries medially 3.

It is cylindrical superiorly, and flattened inferiorly.

Origin of inferior pharyngeal constrictor muscle skin#

insertion: superior border of orbicularis oculi muscle and the overlying skin of the eyebrow there is no attachment to the skull 2 The stylopharyngeus is a long, slender, tapered pharyngeal muscle.origin: anterior end of the galea aponeurotica.Along with the occipitalis muscle, it forms the occipitofrontalis muscle due to a common tendon sheet attachment the galea aponeurotica 1. Flat and quadrilateral in shape, it is one of the facial muscles. These muscles make up the inner layer of musculature - they act to elevate (shorten and widen) the pharynx and larynx during swallowing and speaking. The frontalis muscle ( TA: musculus frontalis) is a paired muscle extending from the supraorbital region to the level of the coronal suture. superior pharyngeal constrictor muscle middle pharyngeal constrictor muscle inferior pharyngeal constrictor muscle Inner/longitudinal muscles.
