Prevalence and pubo-umbilical index of pyramidalis muscle in a select Kenyan population.

Purpose: Pyramidalis is a lower anterior abdominal wall muscle that is considered vestigial and shows variations in prevalence and size. It's been utilized as an anatomical landmark and harvested for use in various surgical procedures. Despite knowledge of its clinical importance, data on the prevalence of pyramidalis remain absent from the Kenyan population with few studies globally reporting on its pubo-umbilical index.

Histomorphological changes in the common carotid artery of the male rat in induced hypogonadism.

The role of androgens in the development of cardiovascular diseases remains controversial. The current study therefore sought to determine the changes in the histomorphology of the common carotid artery of the male rat in orchidectomy-induced hypogonadism. Twenty-two male rats aged 2 months were used.

Variations in the attachments of the medial meniscal anterior horn: a descriptive cadaveric study.

Purpose: Meniscal tears are common in Kenya, with prevalence rates ranging from 45 to 78% of intracapsular knee pathology. Diagnosis of these injuries relies on the use of both clinical signs and symptoms as well as radiological investigations. In a few instances, radiological detection could be difficult, partly because of variant attachment patterns of the medial meniscal anterior horn.

Features of atherosclerosis in the tunica adventitia of coronary and carotid arteries in a black kenyan population.

Introduction. Histologic changes which occur in the tunica adventitia during initiation, progression, and complications of atherosclerosis are seldom reported. This study aimed at describing the features of atherosclerosis in the tunica adventitia of two of the commonly afflicted arteries, namely, left anterior descending coronary and common carotid in black Kenyans.

Pedagogical value of dissection anatomy in Kenya.

Anatomy has historically been a cornerstone in medical education regardless of nation or specialty. Revolution in the training of anatomy has been based on the lack of adequate instructors, cadavers and the general high cost of anatomy training. This has led to the abandonment of dissection by most countries in favour of other methods of learning.

Unusual formation of the median nerve associated with the third head of biceps brachii.

Unilateral variations in the formation of the median nerve, with the presence of the third head of the biceps brachii entrapping the nerve are very rare. These variations were observed on the right side, of a 30-year-old male cadaver during routine dissection at the Department of Human Anatomy, University of Nairobi. The median nerve was formed by the union of three contributions; two from the lateral cord and one from the medial cord.

Variant origin of the superior thyroid artery in a Kenyan population.

Variant anatomy of the superior thyroid artery is important during surgical procedures, interpretation of angiograms, and interventional radiography in the neck. Pattern of the variations shows population differences but there is no data from the Kenyan population. This study therefore investigated the variations in origin of the superior thyroid artery in a Kenyan population.
