Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum. Rock is dissolved by natural acid in groundwater that seeps through bedding planes, faults, joints, and comparable features.
Right side. The perpendicular plate of the ethmoid bone (vertical plate) is a thin, flattened lamina, polygonal in form, which descends from the under surface of the cribriform plate, and assists in forming the septum of the nose; it is generally deflected a little to one or other side.he surfaces of the plate are smooth, except above, where numerous grooves and canals are seen; these lead from the medial foramina on the cribriform plate and lodge filaments of the olfactory nerves.
The lateral epicondyle is a prominent palpable process that projects laterally from the capitellum and is the point of origin of the common extensor tendon. The lateral supracondyle ridge is a bony ridge that runs proximally on the lateral humerus from the lateral epicondyle. The ulnar nerve, which runs in close proximity to the medial epicondyle, often may be palpated as a rounded cord just posterior to this bony prominence. The elbow joint is a hinge-type synovial joint formed where the distal end of the humerus articulates with the proximal ends of the radius and ulna.
