The sensation experienced enters the periphery by axons. More specifically, the sensory axons. This signal passes through axon to axon from the distal to proximal process. The proximal end of the specific axon leads into the spinal cord on the dorsal half. This then moves towards the brain.
Thus the upper arm in humans is proximal and the hand is distal. "Proximal and distal" are frequently used when describing appendages, such as fins, tentacles, and limbs. Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or ...
The difference between punching someone in anger and reaching for a glass is slight in terms of body organization – both rely on extension of the arm. The attention to the strength of the movement, the control of the movement and the timing of the movement are very different.
Standard terms used throughout anatomy include anterior / posterior for the front and back of a structure, superior / inferior for above and below, medial / lateral for structures close to and away from the midline respectively, and proximal / distal for structures close to and far away from a set point.
In this context, a distinction is made between the distal stimulus (the external, perceived object) and the proximal stimulus (the stimulation of sensory organs). [ 1 ] In perceptual psychology , a stimulus is an energy change (e.g., light or sound) which is registered by the senses (e.g., vision, hearing, taste, etc.) and constitutes the basis ...
The zone of proximal development (ZPD) is a concept in educational psychology that represents the space between what a learner is capable of doing unsupported and what the learner cannot do even with support. It is the range where the learner is able to perform, but only with support from a teacher or a peer with more knowledge or expertise.
Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one.It is often tested with two sharp points during a neurological examination [1]: 632 [2]: 71 and is assumed to reflect how finely innervated an area of skin is.
TMT theorists however, have explained how CP dismisses TMT's dual process shown in lab studies whereby proximal and distal defenses deal with threats differently; with the former doing so more "pragmatically" due to greater conscious awareness, and the latter more symbolically due to unconscious thought recession.
