    en.wikipedia.org/wiki/Summation_(neurophysiology)

    Depending on the sum total of many individual inputs, summation may or may not reach the threshold voltage to trigger an action potential. [1] Neurotransmitters released from the terminals of a presynaptic neuron fall under one of two categories, depending on the ion channels gated or modulated by the neurotransmitter receptor.

    en.wikipedia.org/wiki/Suzuki_frame

    The Suzuki frame is a medical device, used for helping heal broken fingers, especially those with deep, complex intra-articular fractures. Rubber bands are used to generate traction between two metal Kirschner wires that are inserted into the bone on either side of a fracture.

    en.wikipedia.org/wiki/Anatomical_snuffbox

    The radius and scaphoid articulate deep to the snuffbox to form the basis of the wrist joint. In the event of a fall onto an outstretched hand (FOOSH), this is the area through which the brunt of the force will focus. This results in these two bones being the most often fractured of the wrist.

    A Smith's fracture, is a fracture of the distal radius. [1] Although it can also be caused by a direct blow to the dorsal forearm [2] or by a fall with the wrist flexed, the most common mechanism of injury for Smith's fracture occurs in a palmar fall with the wrist joint slightly dorsiflexed. [3] Smith's fractures are less common than Colles ...

    The neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. During their lifetime, 2.5% of individuals will experience at least one metacarpal fracture. Bennett's fracture (base of the thumb) is the most common. [4]

  8. Bennett's fracture - Wikipedia

    en.wikipedia.org/wiki/Bennett's_fracture

    The Bennett fracture is an oblique intraarticular metacarpal fracture dislocation, caused by an axial force directed against the partially flexed metacarpal. This type of compression along the metacarpal bone is often sustained when a person punches a hard object, such as the skull or tibia of an opponent, or a wall. It can also occur as a ...
