The dorsal (from Latin dorsum ' back ') surface, (also dorsum) of an organism or organ, refers to the back, or upper side, such as in the human, the dorsum of the tongue, the dorsum of the hand, and the dorsum of the foot. If talking about the skull, the dorsal side is the top. [13] [9]
Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
These terms come from the Latin words with the same meaning. [a] Flexion is a bending movement that decreases the angle between a segment and its proximal segment. [9] For example, bending the elbow, or clenching a hand into a fist, are examples of flexion. When a person is sitting down, the knees are flexed.
The dorsal rami provide motor innervation to the deep (a.k.a. intrinsic or true) muscles of the back, and sensory innervation to the skin of the posterior portion of the head, neck and back. [1] A spinal nerve splits within the intervertebral foramen to form a dorsal ramus and a ventral ramus. The dorsal ramus then turns to course posterior ...
the dorsal palatal consonants (e.g., [ç ʝ ɲ]), such as the ch [ç] in German ich or the ñ [ɲ] in Spanish año; the grooved alveolar consonants (e.g., [s z]), such as the s and z occurring in English words like sip and zip; The first three types of sounds above have a convex tongue shape, which gives them an additional secondary ...

That is, a consonant may be lateral alveolar, like English /l/ (the tongue contacts the alveolar ridge, but allows air to flow off to the side), or lateral palatal, like Castilian Spanish ll /ʎ/. Some Indigenous Australian languages contrast dental, alveolar, retroflex, and palatal laterals, and many Native American languages have lateral ...
The second, third, and fourth dorsal interossei have insertions both proximally on the base of the metacarpal and hood, and distally on the lateral bands and central tendon of the extensor mechanism. The abductor digiti minimi, effectively the "fifth dorsal interosseus" or the dorsal interosseus of the little finger, has only a proximal insertion.
