Spicules Anatomy

Formation of new bone with the development of bony matrix is termed as bone spicules. Spicule nematode anatomy in nematodes roundworms spicules or copulatory spicules are needle like mating structures found only in males.

Male Mating Behavior

Spicule nematode reproductive structures found in male nematodes roundworms.

Spicules anatomy. However others that are noticeable to the human eye are called megascleres. The image on the left is of microscopic spicules known as microscleres. Spicules spicules are spiky spiny structures that serve a structural purpose in most sponges as well as defense against predation.

Accessory reproductive structure in male nematodes. In some species the several spicules that form. A small needle shaped body.

The fibers calcify and encloses to some osteoblasts which eventually leads to the formation of bone spicule. Horny protein gorgonin with calcareous spicules fused to form a solid or jointed central rod. Useful in identification of species.

Spicule glass manufacture glass flakes formed in the production. Located in the ectoderm spicules stiffen the colony. Spicule solar physics jets of solar material from the sun.

Spicule may also refer to. Soft coral spicules are discrete mostly microscopic objects of diverse shapes that vary from needle like to club and anchor shaped. Spicule sponge small skeletal elements of sea sponges.

Males nematodes may have one or two spicules which serve to open the vulva of females and facilitate the transmission of sperm although sperm is not transferred directly by or through the spicules. Such bone spicule is prepared from a network of fibers and calcified deposits interwoven throughout.
