- annulospiral e. one of two types of sensory nerve e. associated with a neuromuscular spindle (the other being the flower-spray e.); after entering the muscle spindle, the fiber divides into two flat, ribbonlike branches that wind themselves in rings or spirals about the intrafusal muscle fibers. SYN: annulospiral organ.

- calyciform e., caliciform e. a synaptic e. in relation to certain neuroepithelial hair cells of the inner ear.

- epilemmal e. a nerve e. in close relation to the outer surface of the sarcolemma.

- flower-spray e. one of the two types of sensory nerve e. associated with the neuromuscular spindle (the other being the annulospiral e.); in this type, the fiber branches spread out upon the surface of the intrafusal fibers like a spray of flowers. SYN: flower-spray organ of Ruffini.

- free nerve endings a form of peripheral e. of sensory nerve fibers in which the terminal filaments end freely in the tissue. SYN: terminationes nervorum liberae.

- grape endings an autodescriptive term applied to synaptic terminals at the ends of short, stalklike axon branches.

- hederiform e. a type of free sensory e. in the skin.

- nerve e. any one of the specialized terminations of peripheral sensory or motor nerve fibers. See motor endplate, corpuscle, bulb.

- sole-plate e. SYN: motor endplate.

- synaptic endings SYN: axon terminals, under terminal.
