INTRODUCTION Myositis ossificans (MO) is characterized as heterotopic bone formation within muscle. MO rarely occurs in the head and neck region. Excision of the heterotopic bone is the standard treatment. This report summarizes a case of a 12-year old female with MO involving the lateral pterygoid muscle. The heterotopic bone was excised using an intraoral incision. Despite intensive physical ...

purpose: to report a patient with exotropia due to medial rectus muscle entrapment as a complication of endoscopic dacryocystorhinostomy (edcr). case report: a 34-year-old female was referred with left exotropia 18 days after edcr for treatment of primary nasolacrimal duct obstruction. she had a large angle left exotropia in primary position as well as complete limitation of adduction and parti...

Introduction The medial thigh muscles –the adductor group– are in the medial compartment of the thigh. The adductor group of thigh muscles consist of adductor longus, adductor brevis, adductor magnus, gracilis and obturator externus muscles. Collectively these muscles are the adductors of the thigh; however actions of some of these muscles are more complex [1]. Pectineus also belongs anatomical...

Recently, the importance of deglutition has attracted attention due to its role in the prevention of aspiration pneumonia. We therefore observed the anatomy of the pharynx of 57 hemi-sections of adult Japanese cadavers (male 32 sides, female 25 sides). A previously unidentified tissue was observed in the infratemporal fossa. This unidentified tissue was a thin membranous tissue that existed bet...

The masticatory and prevertebral muscles of two embryos and four young including a newborn and the pouch of two mothers of the red kangaroo were examined microscopically. Furthermore, four older young of the red kangaroo were examined macroscopically to define the tooth eruption. The results obtained are as follows: 1. The initial muscle spindles are already observed in the prevertebral muscles...

Cyclarhis gujanensis is a little bird which feeds on high number of large preys, such frogs, lizards, snakes, bats and birds. As there are few studies on the cranial anatomy of this species, we aimed to describe the cranial myology to contribute to the anatomical knowledge of this species and to make some assumptions about functional anatomy. Thus, we described the muscles from the jaw apparatu...

Do closely related marsupial herbivores (Diprotodontia) conserve a common masticatory motor pattern or are motor patterns linked to the structure and function of the masticatory apparatus? We recorded the sequence and duration of activity of the individual jaw closing muscles during rhythmic chewing in koalas and then compared their motor pattern with that of their closest extant relatives, wom...
