What's the difference between retinaculum and wrist?
Retinaculum
Definition:
(n.) A connecting band; a fraenum; as, the retinacula of the ileocaecal and ileocolic valves.
(n.) One of the annular ligaments which hold the tendons close to the bones at the larger joints, as at the wrist and ankle.
(n.) One of the retractor muscles of the proboscis of certain worms.
(n.) A small gland or process to which bodies are attached; as, the glandular retinacula to which the pollinia of orchids are attached, or the hooks which support the seeds in many acanthaceous plants.

Wrist
Definition:
(n.) The joint, or the region of the joint, between the hand and the arm; the carpus. See Carpus.
(n.) A stud or pin which forms a journal; -- also called wrist pin.
