Species of Paramecium range in size from 50 to 330 micrometres (0.0020 to 0.0130 in) in length. Cells are typically ovoid, elongate, foot-or cigar-shaped.

- The cricoid cartilage is a ring of cartilage that surrounds the trachea, or windpipe. It is located near the middle and center of the neck. This cartilage consists of strong connective tissue constituting the dorsal (back) part of the larynx, or voice box. The cricoid cartilage is located slightly below the thyroid cartilage, which it connects with through the medial cricothyroid ligament. It also joins the first tracheal ring through the cricotracheal ligament. The thyroid gland has an anatomical relationship with this cartilage.

A Guide to the Cnidarians Cnidarians take on two basic forms, a medusa and a polyp. The medusa form is a free-swimming structure which consists of an umbrella-shaped body (called a bell), a fringe of tentacles that hang from the edge of the bell, a mouth opening located on the underside of the bell, and a gastrovascular cavity.nidarians take on two basic forms, a medusa and a polyp.

- The paramecium is an oval, slipper shaped micro-organism, rounded at the front/top and pointed at the back/bottom. The pellicle, a stiff but elastic membrane that gives the paramecium a definite shape but allows some small changes. Covering the pellicle are many tiny hairs, called cilia. On the side beginning near the front end and continuing half way down is the oral groove. The rear opening is called the anal pore.

Vorticella Return to main Ciliophora page. The Vorticella is a protist (protozoan) and belongs to the Phyllum Ciliophora. It is a very interesting, stalked ciliate with an inverted bell shape. The stalk contains a contractile fibril called a myoneme. When stimulated, it shortens, causing the stalk to coil like a spring.t left you see a close up of the myoneme in action. This was taken with phase contrast. Above, you can see the cilia in a circular pattern around the tip as well as the band shaped nucleus (shape of a C) inside the protist. The Vorticella is a protist (protozoan) and belongs to the Phyllum Ciliophora.

Female Gonads The mesovarium, which is a double layer of peritoneum, secures the ovary at its anterior surface to the posterior part of the broad ligament. With the exception of this part of the ovary, the rest of the organ is covered by a sheath of cuboidal epithelium and not peritoneum. The posterior surface of the ovary is exposed to the peritoneal cavity. Its medial border is related to the uterosacral fold as well as the body of the uterus. Finally, the lateral surface of the ovary is related to the angle of the internal and external iliac vessels, the ureteric fold and the obturator nerve.

Bacterial Cell Cell Wall: Composed of peptidoglycan (polysaccharides + protein), the cell wall maintains the overall shape of a bacterial cell. The three primary shapes in bacteria are coccus (spherical), bacillus (rod-shaped) and spirillum (spiral). Mycoplasma are bacteria that have no cell wall and therefore have no definite shape. Outer Membrane: This lipid bilayer is found in Gram negative bacteria and is the location of lipopolysaccharide (LPS) in these bacteria.

Clinodactyly Clinodactyly /ˈklaɪnˌoʊdæktɪli/ (from the Ancient Greek κλίνειν klínein meaning to bend and δάκτυλος dáktulos meaning digit) is a medical term describing the curvature of a digit (a finger or toe) in the plane of the palm, most commonly the fifth finger (the little finger) towards the adjacent fourth finger (the ring finger).

Crinoids This is part of the stem of a crinoid, from the side and from the top. They used to be called St Cuthbert's Beads. St Cuthbert lived at Lindisfarne, and was supposed to use the fossils as rosary beads. In Derbyshire, they are called screwstones, as the shape looks like a screw. However, the grooves don't make a spiral like a proper screw. Some crinoid stems have the shape of a star, and they are called star stones.

Crinoids can be tricky to identify if you only have a few segments; only certain segments can be easily identified. However it is easier to identify the Crown. Crinoids are starfish-related animals. Camerata crinoidea is identified by it's unique 3 mini Calyx. Unlike most Crinoids it's arms conect to the secondary Calyx that conect to the main Calyx. 35 cm is a decent size for a Camerata crinoidea. The primary Calyx supports 3 mini Calyx, the arms are atached to the mini Calyx.

Actinosphaerium The Actinosphaerium is a protist (protozoan) and belongs to the Phyllum Sarcodina. It looks like a sea urchin and is from 200-1000 micrometers wide. This is quite large for a protists. The image below (left) shows a close up of the endoplasm and ectoplasm, the water expelling vesicles (WEV) and how this protists uses the radial arms to move by flowing the protoplasm into the arms.

Acrosome The acrosome is an organelle that develops over the anterior half of the head in the spermatozoa (sperm cells) of many animals. It is a cap-like structure derived from the Golgi apparatus. Acrosome formation is fully completed 5–10 years after testicular maturation. [citation needed] In Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin). These enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.

Cricoid cartilage The cricoid cartilage /ˌkraɪkɔɪd ˈkɑːrtɪlɪdʒ/ , or simply cricoid (from the Greek krikoeides meaning ring-shaped), is the only complete ring of cartilage around the trachea.nferior to it are the rings of cartilage around the trachea (which are not continuous-rather they are C-shaped with a gap posteriorly). The cricoid is joined to the first tracheal ring by the cricotracheal ligament, and this can be felt as a more yielding area between the firm thyroid cartilage and firmer cricoid.

- Description: About one inch long. Spiral shell is typically black, brown, or gray. The common periwinkle, which first appeared in New England in the 1860s, is now found along the coast wherever there’s hard substrate–rocks, riprap, broken concrete, or docks–from Labrador to Maryland.About the diameter of a quarter, the snail can be recognized by the blunt shape of its shell and a white inner lip.dd spaghetti, and remove when soft but still firm to the bite. At the same time that you add the spaghetti, add the periwinkles to the sauce. Mix the pasta and sauce in a warm bowl. Serve hot, with crusty Italian bread and grated Parmesan cheese.

Clinical Anatomy of the Uterus, Fallopian Tubes, and Ovaries Lymphatic drainage of the uterus and upper two-thirds of the vagina is primarily to the obturator and internal and external iliac nodes. The fallopian tubes are bilateral muscular structures of paramesonephric duct origin. They are from 7 to 12 cm in length and usually less than 1 cm in diameter. The tubes or oviducts have a lumen that varies considerably in diameter.
