A list of reflexes in humans. Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.
The fastest reflex recorded in humans happens within the masseter muscle or jaw muscle. The reflex was measured by electromyography which records the electrical activity during movement of the muscles. This also showed the response latency, or the delay between the stimulus and the response recorded, was found to be about 14 milliseconds.
Like the reflex, a positive fencing response resembles the en garde position that initiates a fencing bout, with the extension of one arm and the flexion of the other. Tonic posturing preceding convulsion has been observed in sports injuries at the moment of impact [ 2 ] [ 3 ] where extension and flexion of opposite arms occur despite body ...
Agility or nimbleness is an ability to change the body's position quickly and requires the integration of isolated movement skills using a combination of balance, coordination, speed, reflexes, strength, and endurance. More specifically, it is dependent on these six skills:
Most reflexes can be categorized in one of three groups depending on the latency of EMG response. The short-latency reflex (SLR) is the fastest (~40-50 ms) and involves a mono-synaptic pathway. The medium-latency reflex (MLR) utilizes interneurons within the spinal cord and is typically ~80-90 ms. The long-latency reflex (LLR) is ~120-140 ms ...
Symptoms associated with central nervous systems disorders are classified into positive and negative categories. Positive symptoms include those that increase muscle activity through hyper-excitability of the stretch reflex (i.e., rigidity and spasticity) where negative symptoms include those of insufficient muscle activity (i.e. weakness) and reduced motor function.

Diving reflex in a human baby. The diving reflex, also known as the diving response and mammalian diving reflex, is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, and is found in all air-breathing vertebrates studied to date.
The most common anecdotal examples based on hearsay are of parents lifting vehicles to rescue their children, and when people are in life-and-death situations. Periods of increased strength are short-lived, usually no longer than a few minutes, and might lead to muscle injuries and exhaustion later.
