The distal phalanges on their palmar surface are flat, small and with a roughened, elevated surface of horseshoe, supporting the digital pulp. The tips of these phalanges, called apical tuffs, are flat and wide. The thumb gives an insertion for the flexor pollicis longus or FPL, ungual fossa, and a pair of ungual spines. The assymmetrical feature of the FPL make sure that the thumb pulp is always facing the pulps of the other digits, which provides the optimum contact surface with held
a biology class wants to perform an experiment to investigate the effect of different colors of light of green, yellow, red and clear cellophane and plant three seeds in each one. What part do the three seeds experiment? A,Confounding variables B.Independent variables C.Control variables D.Dependent variables 40. Iodine directly helps which of the following glands to function properly?
However no variation in relation with piriformis and level of terminal division was observed in foetuses. The length of sciatic nerve in foetuses varied from 7.1 cm to 8 cm on both sides. The breadth of the nerve varied from 0.2 cm to 0.35 cm on the right side and 0.19 cm to 0.3 cm on the left side. The thickness of the sciatic nerve ranged from 0.09 cm to 0.12 cm on both
The uterine tubes, otherwise called oviducts or fallopian tubes, are the female structures that vehicle the ova from the ovary to the uterus every month. In the vicinity of sperm and treatment, the uterine tubes transport the treated egg to the uterus for implantation.the uterine tubes are uterine limbs spotted reciprocally at the predominant bit of the uterine cavity. These tubes retreat the uterus through a territory alluded to as the cornua, structuring an association between the endometrial and peritoneal cavities. Every uterine tube is roughly 10 cm long and 1 cm in measurement and is arranged inside the mesosalpinx. The mesosalpinx is a fold in the expansive ligament.
Polyclonal B-cell hyperreactivity with abnormalities of autoregulation have been reported, the histopathologic substrate of Sjogren’s syndrome is characterized by presence of lymphocytic infiltrates in glandular and extraglandular sites. Microscopic examinations of enlarged parotid or submandibular glands reveal benign lymphoepithelial lesion, characterized by epimyoepithelial islands in a lymphocytic infiltrate with replacement of acini. In the minor salivary glands the characteristic feature is focal lymphocytic
The parathyroids are small lentiform glands which normally measure approximately 6 mm in length, 3-4 mm in transverse diameter, and 1-2 mm in antero-posterior direction (Policeni et al., 2012). The weight of the parathyroid gland can vary from 10 - 78mg with an average weight of just 40mg (Gilmour & Martin, 1987). When normal in size, the glands are not easily identified on most imaging studies. In contrast, in gland hyperplasia or with parathyroid adenomas the glands are generally larger and therefore more readily identified on imaging studies. In general people have two superior and two inferior glands, which sit in pairs either side of the midline.
Also, the same group reported that deletions in L-type calcium channel α-1 subunit testicular transcripts correlated with testicular cadmium content and apoptosis in infertile men with varicocele((Benoff et al.,2012), Thus, these authors hypothesized that an infertile man with a varicocele has a specific genetic or environmentally induced defect that causes infertility and that varicoceles interact with these defects to exacerbate the already reduced fertility potential. Cadmium exposure and its accumulation are known to impair spermatogenesis, sperm function and lead to impaired reproductive potential in men( Goodwin et
Our foot consists of 26 bones, 33 joints, 100+ muscles, tendons & ligaments, artery, and all these are covered by a supportive thick skin. Foot Bones Total 26 bones locate in three main portions of our foot: Forefoot, Mid-foot, and Hind-foot. It separates into three parts; tarsals, meta-tarsals, and Phalanges. https://en.wikipedia.org/wiki/File:Calcaneus_animation01.gif Tarsal Bones
Each renal artery is divided into anterior and posterior branches (presegmental arteries) at the hilium of the kidney. The further division of the arteries is into following branches apical, upper, middle, inferior and posterior. ARTERIAL VARIATIONS It has been established that each of the segments is supplied by their own segmental artery without any collateral connection therefore the importance of each and every branch is equal and needs proper evaluation(33).
While matrix is a substance that embedded the cells. Connective tissue appear in various type throughout the human body but it is never been exposed to the outside environment. (Frederic H. Martini, William C.Ober, Judi L.Nath, Edwin F.Bartholomew, & Kevin Petti, 2015)In foetuses and embryos, there were embryonic tissue. After birth, there is mature connective tissue. Mature connective tissue consists of three components and can be divided into six types.
The posterior lobe is then responsible for storing the hormones made by the neurons of the hypothalamus. The hypothalamo-hypophyseal portal system is the specific way the hypothalamus communicates with the anterior lobe of the pituitary gland. This portal system consists of blood vessels that carry hormones of the hypothalamus to the anterior lobe. The anterior lobe then responds by making its own hormones. The anterior lobe hormones can go and control other glands.
Head and body lengths of adults average from 9.7 cm-13.2 cm. However, in the wild the average is much higher at 24.3 cm in males and 23.0 cm in females. Many species are sexually dimorphic, which means the males are larger than the females. Tarsier have a particular spinal morphology that allows them to turn their heads a whopping 180° in each direction. Their legs and their muscles make up about a quarter of their total body weight.
