We made intraaxonal recordings from 30 individual globular bushy cell axons in the trapezoid body of the cat using HRP-filled glass microelectrodes. With subsequent HRP injection, we determined their axonal projection patterns. For cells with characteristic frequencies (CFs) above 3 kHz, short-tone peristimulus time histograms (PSTHs) at CF were typically primarylike at low tone intensities and...

MeThODS In 16 cadavers, the motor innervations of the orbicularis oculi muscle (m.OO) were studied. Multiple anastomoses between the 3 buccal branches were noticed within the medial two-thirds of the lower lid just below the arcus marginalis. They did not anastomose with the zygomatic branch, which tangentially entered the m.OO in front of the lateral canthus. Hence, the safety of m.OO undermin...

BACKGROUND The anterior approach to the hip gained popularity for total hip arthroplasty in recent years. Distal extension of the anterior approach, sometimes needed intraoperatively, potentially endangers neurovascular structures to the quadriceps. The aim of this study was to determine the anatomical structures placed at risk by distal extension of the anterior approach to the hip. METHODS ...

The facial artery (FA) normally arises from the external carotid artery (ECA), just above the lingual artery, at the level of greater horn of hyoid bone in the carotid triangle. It then passes obliquely upwards beneath the posterior belly of digastric and stylohyoid muscles sheltered by the ramus of the mandible lying medial to the bone. Here it passes deep to the superficial part of the subman...

In order to investigation of vermicompost effect on growth and yield of marigold in pot medium, an experiment was done by a randomized completely block design in three raplications. Treatmnets were included control (30% v/v of soil plus 70% v/v of sand) and three levels of vermicompost (20, 40, 60 % v/v of vermicompost+30% v/v of sand and soil) that applied in three lit. pots. Marigold seeds (T...

Variations of venous pattern in the arm are common. In this case report, we present a variation of axillary artery and vein. During routine educational dissections of axillary region, it was observed that a fenestrated axillary vein was perforated by a variant axillary artery in right arm of an old male cadaver. The axillary artery which was fenestrated through axillary vein had only two branch...

An unusual unilateral variation in the branching pattern of axillary artery was observed in a 60 year old female embalmed cadaver. The axillary artery had only two branches arising from its proximal (first) part and no branches from its remaining distal (second & third) parts. The branches are superior thoracic (usual) and another large collateral (unusual) branch. This collateral branch is the...

Variations in the anatomy of the lateral femoral cutaneous nerve (LFCN) have been reported in the literature. LFCN is vulnerable to injury during several surgical operations, therefore any surgeon intervening in the area should be familiar to its topographic variability. Lesion of the nerve leads to a condition known as "meralgia paresthetica". We present a cadaveric case of a variant LFCN wher...

Introduction Axillary artery begins as a continuation of 3rd part of subclavian artery at the outer border of the first rib. It extends at the lower border of teres major muscle where it continues as the brachial artery. The pectoralis minor muscle divides the axillary artery into three parts. It usually gives off 6 branches. The 1st part which is medial to pectoralis minor muscle gives superio...
