  2. Thenar eminence - Wikipedia

    en.wikipedia.org/wiki/Thenar_eminence

    The ulnar nerve is exclusively responsible for the innervations of the hypothenar eminence. Both nerves contribute to the innervations of the midpalmar group. [8] The innervation of these muscles by the median nerve is unusual, as most of the intrinsic muscles on the palm of the hand are supplied by the ulnar nerve.

  3. Muscles of the hand - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_the_hand

    The median nerve innervates the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbricals. The ulnar nerve innervates the remaining intrinsic muscles of the hand. [3] [4] All muscles of the hand are innervated by the brachial plexus (C5–T1) and can be classified by innervation: [1] [4] [5]

  4. Proprioception - Wikipedia

    en.wikipedia.org/wiki/Proprioception

    Proprioception of the head stems from the muscles innervated by the trigeminal nerve, where the general somatic afferent fibers pass without synapsing in the trigeminal ganglion (first-order sensory neuron), reaching the mesencephalic tract and the mesencephalic nucleus of trigeminal nerve. [26]

  5. Proprioception and motor control - Wikipedia

    Central pattern generators are groups of neurons in the spinal cord that are responsible for generating stereotyped movement. It has been shown that in cats, rhythmic activation patterns are still observed following removal of sensory afferents and removal of the brain., [1] indicating that there is neural pattern generation in the spinal cord independent of descending signals from the brain ...

  6. Cervical spinal nerve 8 - Wikipedia

    en.wikipedia.org/wiki/Cervical_spinal_nerve_8

    The C8 nerve contributes to the motor innervation of many of the muscles in the trunk and upper limb. 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.

  7. Somatosensory system - Wikipedia

    en.wikipedia.org/wiki/Somatosensory_system

    They are responsible for the feeling of object slippage and play a major role in the kinesthetic sense and control of finger position and movement. Merkel and bulbous cells - slow-response - are myelinated; the rest - fast-response - are not. All of these receptors are activated upon pressures that distort their shape causing an action potential.

  8. Hypothenar eminence - Wikipedia

    en.wikipedia.org/wiki/Hypothenar_eminence

    The muscles of hypothenar eminence are from medial to lateral: Opponens digiti minimi; Flexor digiti minimi brevis; Abductor digiti minimi; The intrinsic muscles of hand can be remembered using the mnemonic, "A OF A OF A" for, Abductor pollicis brevis, Opponens pollicis, Flexor pollicis brevis (the three thenar muscles), Adductor pollicis, and the three hypothenar muscles, Opponens digiti ...

  9. Dorsal interossei of the hand - Wikipedia

    en.wikipedia.org/wiki/Dorsal_interossei_of_the_hand

    Each finger is provided with two interossei (palmar or dorsal), with the exception of the little finger, in which the abductor digiti minimi muscle takes the place of one of the dorsal interossei. [2] The first dorsal interosseous muscle is larger than the others. Between its two heads, the radial artery passes from the back of the hand into ...
