Tail sheath acts as a cell membrane to the sperm.
the tail sheath is eaten by chinease people
how the sperm cells structure is linked to the cells function, the tall sheath?
The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

It is used for protection against the outside environment
Since Fucus lives in intertidal regions, the gelatinous sheath probably prevents desiccation.
The function of bundle sheath is to facilitate various processes in the plants. Some of the roles include fixation of carbon during photosynthesis and transportation within the plant among others.The bundle sheath separates the vascular bundle from the ground tissue.
myelin sheath
allows the exit of hairs through the epidermal surface
the function of a tail is to lift its body and to increase the speed of flight
The myelin sheath acts as a covering on the axon of a neuron just as the covering on the cord you plug into an electrical socket. If it is damaged, the current can be "short circuited" and the neuron and the axon will not function. This sheath allows impulses to travel rapidly. MS is a disease where these sheaths are damaged.
The general structure of a bacteriophage includes a head, tail sheath, and tail fiber. It uses its tail fibers to bind to a receptor site of a bacteria cell.
