Finger waves are similar to the marcel wave in appearance and are easily confused. Unlike finger waves, the marcel wave is made with a hot curling iron, and is more permanent than finger waves. [6] Another hairstyle often confused with finger waves is the croquignole method of curling hair used to create a permanent wave. In this method the ...
In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...
François Marcel marcelling his wife's hair, 1922. Marcelling is a hair styling technique in which hot curling tongs are used to induce a curl into the hair. [1] [2] Its appearance was similar to that of a finger wave but it is created using a different method.
In biology, dactyly is the arrangement of digits (fingers and toes) on the hands, feet, or sometimes wings of a tetrapod animal. The term is derived from the Greek word δακτυλος (dáktylos) meaning "finger." Sometimes the suffix "-dactylia" is used. The derived adjectives end with "-dactyl" or "-dactylous."
Until recently this proposed function was controversial and hard to prove, due to the close physical association of Merkel cells with sensory nerve endings. However, recent work in mice and other model organisms demonstrates that Merkel cells intrinsically transform touch into electrical signals that are transmitted to the nervous system. [ 9 ]
The AEF potentially functions as an inhibitor to fin outgrowth since removing the AEF results in the formation of a new AER and subsequently a new AEF. In addition, repeated AF removal leads to excessive elongation of the fin mesenchyme, potentially because of prolonged exposure of AER signals to the fin mesenchyme. [ 16 ]
Transcriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. [ 5 ] [ 6 ] CTCF is involved in many cellular processes, including transcriptional regulation , insulator activity, V(D)J recombination [ 7 ] and regulation of chromatin architecture.
William Birnbaum with a Phonocardiogram System for use in Project Gemini, 1965. Awareness of the sounds made by the heart dates to ancient times. The idea of developing an instrument to record it may date back to Robert Hooke (1635–1703), who wrote: "There may also be a possibility of discovering the internal motions and actions of bodies - whether animal, vegetable, or mineral, by the sound ...
