the author presents an unusual extension of the cerebrospinal fluid space into the proximal tympanic part of the facial nerve, and points out the clinical and surgical significance of this anatomical variation.

Introduction The hamstring muscles are frequently implicated in posterior thigh pain due to strains. The hamstring muscles are the three most superficial muscles that span the posterior thigh, and consist of the biceps femoris, semitendinosus, and semimembranosus. The long head of biceps femoris originates from the inferiomedial aspect of the ischial tuberosity and inserts into the head of the ...

PURPOSE To examine the anatomical variation of normal human collector channel orifices and their relationship with Schlemm's canal. METHODS Ten human anterior segments fixed by immersion or perfusion were dissected radially and further divided by fine dissection into corresponding inner and outer wall segments. The tissues were dehydrated, critical-point dried, sputter coated, and examined by...

Anatomical variations are naturally-occurring deviations from typical human anatomy. While these variations are considered normal and non-pathological, they are still of interest in clinical practice for medical specialists such as radiologists and transplantation surgeons. The complex variations in branching structures, for instance in arteries or nerves, are currently visualized side-by-side ...

OBJECTIVE To observe the topographic localization of the brachial artery termination. METHODS This study was conducted at the Department of Anatomy, Faculty of Medicine, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia from December 2011 to February 2013. The bifurcation level of the brachial artery was determined in relation to the neck of the radius. Normal and abnormal terminatio...

Infraorbital nerve, a terminal branch of maxillary division of the trigeminal nerve, exits the infraorbital foramen or notch, providing sensory innervations to the skin and soft tissue of the mid face. Adequate knowledge of the location of the nerve and assessment of its function are important in mid face surgeries and reaching optimal local anesthesia. The location of the infraorbital foramen ...
