In vitro muscle testing can be done on any scale of muscle organization - entire groups of muscles (provided they share a common insertion or origin, as in the human quadriceps), a single muscle, a "bundle" of muscle fibers, a single muscle fiber, a single myofibril, a single sarcomere, a cardiomyocyte or even a half-sarcomere. Muscle fibers ...
The test involves monitoring internal/external anal sphincter contraction in response to squeezing the glans penis or clitoris, or tugging on an indwelling Foley catheter. This reflex can also be tested electrophysiologically, by stimulating the penis or vulva and recording from the anal sphincter.
Its primary function is the flexion of the fingers, and this is used as the clinical test for C8 integrity, in conjunction with the finger jerk reflex. [4] The particular muscles receive innervation from C8 [3] (shown by specific nerve and spinal nerve segments; muscles in italics only have a minor contribution from C8) :
Vulpes is a genus of the sub-family Caninae. The members of this genus are colloquially referred to as true foxes , meaning they form a proper clade . The word " fox " occurs in the common names of all species of the genus, but also appears in the common names of other canid species.
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
They obtained a set of de-afferented muscle spindles, measured their response to a series of sinusoidal and step function stretches, and fit a transfer function to the spike rate. They found that the following Laplace transfer function describes the firing rate responses of the primary sensory fibers for a change in length:
A flexion test is a preliminary veterinary procedure performed on a horse, generally during a prepurchase or a lameness exam. The purpose is to accentuate any pain that may be associated with a joint or soft-tissue structure, allowing the practitioner to localize a lameness to a specific area, or to alert a practitioner to the presence of sub-clinical disease that may be present during a pre ...
Infrequently, a child is born with a "soft tail", which contains no vertebrae, but only blood vessels, muscles, and nerves, but this is regarded as an abnormality rather than a vestigial true tail, even when such an appendage is located where the tail would be expected.
