Gross Anatomy Assignment Name: Olorunfemi Peace Toluwalase Matric No: 17/Mhs01/257 Dept: Mbbs Course: Gross Anatomy of Head and Neck
GROSS ANATOMY ASSIGNMENT NAME: OLORUNFEMI PEACE TOLUWALASE MATRIC NO: 17/MHS01/257 DEPT: MBBS COURSE: GROSS ANATOMY OF HEAD AND NECK QUESTION 1 Write an essay on the carvernous sinus. The cavernous sinuses are one of several drainage pathways for the brain that sits in the middle. In addition to receiving venous drainage from the brain, it also receives tributaries from parts of the face. STRUCTURE ➢ The cavernous sinuses are 1 cm wide cavities that extend a distance of 2 cm from the most posterior aspect of the orbit to the petrous part of the temporal bone. ➢ They are bilaterally paired collections of venous plexuses that sit on either side of the sphenoid bone. ➢ Although they are not truly trabeculated cavities like the corpora cavernosa of the penis, the numerous plexuses, however, give the cavities their characteristic sponge-like appearance. ➢ The cavernous sinus is roofed by an inner layer of dura matter that continues with the diaphragma sellae that covers the superior part of the pituitary gland. The roof of the sinus also has several other attachments. ➢ Anteriorly, it attaches to the anterior and middle clinoid processes, posteriorly it attaches to the tentorium (at its attachment to the posterior clinoid process). Part of the periosteum of the greater wing of the sphenoid bone forms the floor of the sinus. ➢ The body of the sphenoid acts as the medial wall of the sinus while the lateral wall is formed from the visceral part of the dura mater. CONTENTS The cavernous sinus contains the internal carotid artery and several cranial nerves. Abducens nerve (CN VI) traverses the sinus lateral to the internal carotid artery. -

Injection Into the Longus Colli Muscle Via the Thyroid Gland
Freely available online Case Reports Injection into the Longus Colli Muscle via the Thyroid Gland Małgorzata Tyślerowicz1* & Wolfgang H. Jost2 1Department of Neurophysiology, Copernicus Memorial Hospital, Łódź, PL, 2Parkinson-Klinik Ortenau, Wolfach, DE Abstract Background: Anterior forms of cervical dystonia are considered to be the most difficult to treat because of the deep cervical muscles that can be involved. Case Report: We report the case of a woman with cervical dystonia who presented with anterior sagittal shift, which required injections through the longus colli muscle to obtain a satisfactory outcome. The approach via the thyroid gland was chosen. Discussion: The longus colli muscle can be injected under electromyography (EMG), computed tomography (CT), ultrasonography (US), or endoscopy guidance. We recommend using both ultrasonography and electromyography guidance as excellent complementary techniques for injection at the C5-C6 level.

This study described changes in the following structures: retromandibular vein and its divisions, including the relationship with the facial nerve, facial vein, common facial vein and jugular veins. Material and Methods: The variations of the veins were analyzed in three heads, five hemi-heads (right side) and two hemi-heads (left side) of unknown age and sex. Results: The changes only on the right side of the face were: union between the superficial temporal and maxillary veins at a lower level; absence of the common facial vein and facial vein draining into the external jugular vein. While on the left, only, it was noted: posterior division of retromandibular, after unite with the common facial vein, led to the internal jugular vein; union between the posterior auricular and common facial veins to form the external jugular and union between posterior auricular and common facial veins to terminate into internal jugular. -

The levator claviculae muscle was observed with intact nerve supply from the ventral ramus of C3, indicating its functional status. The muscle was lambda (λ)-shaped with its stem oriented cranially, attaching to the fascia of the longus capitis muscle at the level of the transverse process of the fourth cervical vertebra. More inferiorly, the stem splits into a pars medialis and pars lateralis each with fascial attachments to the clavicle within the middle third of the bone. Both parts had fascial attachments to the clavicle within the middle third of the bone, and the lateral part passed medial to the external jugular vein.
