The locking is completed by circular muscles just inside the female's vagina; this is called "the knot" tightening thus preventing the male from withdrawing. The circular muscles also contract intermittently, which has the effect of stimulating ejaculation of sperm, followed by prostatic fluid, as well as maintaining the swelling of the penis ...
The penile sheath entirely surrounds the glans while not erect. The back part is intergrown with the abdominal skin. The front part, almost reaching to the navel, is free. The inner sheath, just like the glans, is covered with a mucous membrane and the outer sheath is covered with normal, hairy epidermis.
The dogshank, or sheepshank pouch knot, is a variant of the sheepshank where the eyes formed at each end have the ends of the rope passed through them to prevents the knot from spilling. At least one end of the rope must be available to tie or untie this knot. It is mostly useful for the hammock-like space it creates. [4]
However, it places more bends in a rope than other belay methods, and creates significantly more friction on the outer sheath. Another disadvantage is that it can introduce significant twists to the rope. It is a versatile knot to know and can be used for full rope length vertical descents without the need for gloves.
In one extreme case, a ganglion cyst was observed to propagate extensively via the conduit of the common peroneal nerve sheath to a location in the thigh; in such cases surgery to the proximal joint to remove the articular connection may remove the need for a riskier, more extensive surgery in the neural tissue of the thigh.

The slipped form of the buntline hitch (on the right) can easily be untied by pulling the hanging end and withdrawing the loop. A slipped knot is any knot that unties when an end is pulled. Thus, tying the slipped form of a knot makes it easier to untie, especially when the knot is prone to jamming. [1] A slip knot is just one variety of ...
An aglet (/ ˈ æ ɡ l ə t / AG-lət) [1] or aiglet is a small sheath, often made of plastic or metal, attached at each end of a shoelace, a cord, or a drawstring. [2] An aglet keeps the fibers of the lace or cord from unraveling; its firmness and narrow profile make it easier to hold and easier to feed through eyelets , lugs, or other lacing ...
The pipe hitch will not slip when tied correctly to a pipe or pole. This knot is a variation of the Round turn and two half-hitches. [4] [5] This knot can be used with a rope to pull a pipe or spar out of the ground, [6] or to hoist a pipe or beam.
