Abstract:
We determined asymmetry, complexity and pattern polarization of dermal ridges and palmar variables of atd angle, a - b ridge count and total finger ridge count of dermal ridges among the Ndokwa people of Nigeria. 400 healthy students who are Ndokwas were studied. Ink prints of their fingers and palms were obtained. Counting and classifying of Palmar and digital ridge pattern configurations of arches, loops and whorls was based on standard techniques. Ulnar loops polarized preferentially to digits III, IV and V and radial loops to digit II. Female subjects had higher counts of radial loops (p < 0.001) than the males. Male subjects had a higher whorl count than the females (p < 0.05). Our findings form useful baseline data for subsequent longitudinal cytogenetic studies on the Ndokwa people.

Accessory Structures of the Skin: Nails
The main components of a nail include the following.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
