The lateral femoral cutaneous nerve (LFCN), a branch from the lumbar plexus, may come to the clinician's or surgeon's attention. We studied this nerve to determine its location and its relationship with neighboring structures around the anterior superior iliac spine (ASIS) and the inguinal ligament (IL). Additionally, cross-sectional microanatomy of the LFCN at the IL was studied. The LFCN was dissected in 47 lower limbs from formalin-fixed cadavers. The distances from the ASIS to the point where the LFCN crossed the IL and the lateral border of the sartorius were measured. The distance between the ASIS and the point it pierced the deep fascia was also measured. Twelve nerve specimens at the IL were collected for histological sectioning and were stained with hematoxylin and eosin. On examination of the cross-sectional area, the nonfascicular area was wider than the fascicular area because of an increased amount of thick collagen fibers. This study may be of help to clinicians managing meralgia paresthetica and may also assist in defining a safe area for surgical intervention on the anterolateral aspect of the thigh.
Background: External surface of lips has many elevations and depressions forming a characteristic pattern called lip prints, the study of which is known as cheiloscopy. This is unique for the individuals like in fingerprints.Methods: The present study was conducted in 40 pairs of twins and their families to evaluate the possibility of variation of lip print patterns in twins and their parents to find out any similarity among twins and their families. The twins were taken as the primary subject and their parents as the secondary subjects.Results: The subjects with congenital lip deformity and any inflammation were excluded from the study. The lip prints were taken on the cello tape and highlighted with the black printer powder of Oddyessy make. the photographs were taken for the permanent record. The prints were studied on Adobe Photoshop 7.0 software and classified under Tsuchihashi classification.Conclusions: Comparison of lip prints showed that they are unique to each individual and among twins revealed that they are similar but not identical and their characteristics resembled either parent. Since the lip print patterns are unique, lip print analysis can be considered as a tool for personal identification.
Both aluminium and ethanol are pro-oxidants and toxic. Uncontrolled use of aluminium and increasing trends of ethanol consumption in India increased the chance of coexposure to aluminium and ethanol. There are possibilities, that both of them follow common mechanisms to produce reproductive toxicity. The present study was planned to identify the effects of aluminium administration on the microscopic structure of ovary and to clarify any possible protection conferred by the concomitant administration of ethanol. Sixteen female rats divided into one control and three experimental groups exposed to aluminium (4.2mg/kg body weight) and ethanol (1gm/kg body weight) for 3 months. After the exposure period, ovaries were processed for light microscopic examination. Ovary showed significant atretic follicles with degenerated ova and vacuolation. Rupture of zona pellucida in oocyte seen in aluminium treated animals. Ethanol treated group showing absence of growing follicles, increased large corpora lutea. Dilated and congested vessels were observed in the growing follicle. The effects of combined administration of aluminium and ethanol treated groups showed with acute degeneration of growing follicles, with desquamation of pyknotic granulosa cells and degenerated oocyte. Multiple vacuoles of degenerated granulosa cells with dilated congested vessels and edema seen. Hyaline material seen inside the degenerating follicles. It has been suggested that the ethanol induced augmentation of impacts of aluminium on the Ovary.
A tendinous origin and fleshy insertion of palmaris longus muscle was observed in the left forearm during routine dissection which was performed on adult male cadaver in the department of Anatomy, Dr. Rajendra Prasad Government Medical College. It was having long tendinous origin from the medial epicondyle of the humerus and the surrounding deep fascia. It was fusiform at the lower middle of the forearm. The fleshy muscular insertion was noted to the flexor retinaculum and few muscular fibers interdigitate with flexor carpi ulnaris muscle and palmar aponeurosis. The length of tendon was 19 inches and fleshy muscular length was 11inches. The median nerve and ulnar nerve was covered by this fleshy insertion. This palmaris longus variation is helpful for the surgeon and the radiologist, orthopaedic, plastic surgeon during any diagnosis of the forearm because this fleshy part of muscle can compress the median nerve and ulnar nerve or it can be mistaken as a tumor or ganglion during radiological or clinical examination.
Introduction: Variation of the ulnar artery in the upper limb is uncommon. The existence of such a variant is of particular clinical significance, as these arteries are more susceptible to trauma, and can be easily confused with superficial veins during medical and surgical procedures, potentially leading to iatrogenic distal limb ischemia. Case report: During routine dissection we observed a unilateral case of superficial ulnar artery in a 60-year-old male cadaver. It originated from the left brachial artery in the middle of the arm, near to insertion of coracobrachialis muscle. From its origin, it passed downwards in the medial part of arm behind the median nerve and forearm in a supericial plane compared to normal ulnar artery. In the hand, the supericial ulnar artery anastomosed with the palmar branch of the radial artery, creating the supericial palmar arch. Brachial artery divided into the radial and common interosseous arteries in the cubital fossa. The normal ulnar artery was absent. The existence of superficial ulnar artery is undeniably of interest to the clinicians as well as to the anatomists.
