Cervical Osteophytes: Bone Spurs in the Neck

Cervical osteophytes are bone spurs that grow on any of the seven vertebrae in the cervical spine (neck), ranging from the base of the skull, C1 vertebra, to the base of the neck, C7 vertebra. While most cervical bone spurs are harmless, sometimes they can cause neck pain and stiffness. Watch Cervical Bone Spurs Symptoms and Causes Animation.

Can a symmetrical body experience lift force?

Yes, a symmetrical body can experience lift. Aerodynamic lift depends on the speed of air being different on either sides of the object. On an aerofoil (eg aircraft wings) this is accomplished by the asymmetric shape of the airofoil. But if we can...

Phylum Echinodermata | manoa.hawaii /ExploringOurFluidEarth

Echinoderms are radically symmetrical, and the body is usually divided into five parts or multiples of five. This five-sided radial structure of echinoderms makes the body strong (Fig. 3.86). A five-sided skeleton is stronger than a four- or six-sided one because the line of weakness cannot run directly across the body.

Features Used to Classify Animals | Biology II

Bilateral symmetry involves the division of the animal through a sagittal plane, resulting in two mirror image, right and left halves, such as those of a butterfly (Figure 2d), crab, or human body. Animals with bilateral symmetry have a "head" and "tail" (anterior vs. posterior), front and back (dorsal vs. ventral), and right and left sides (Figure 3).

Double Crush Syndrome : JAAOS

a peripheral nerve. Double crush syndrome is a controversial diagnosis; some scientists and surgeons believe it is an illness construction that may do more harm than good because it emphasizes an objective pathophysiologic explanation for unexplained symptoms, disability, and dissatisfaction that may be more psychosocially mediated. However, peripheral neuropathy may coexist with compressive ...

Fracture general principles

A fracture is generally visible in one direction only. Therefore, never settle for an image in only one direction. If bone fragments are displaced as a result of a fracture, the X-ray beam will not be absorbed by the bone at the fracture site (= the gap) (fig. 1a). This is visible as a lucent line (= black line).

Intermediate

Lateral folding of the embryo brings the heart tubes into the ventral midline, allowing them to fuse to form a single primordial heart tube. Fusion of the heart tubes begins cranially and extends caudally and is facilitated by apoptosis.The animation below shows a cross section of the embryo and the development of the endocardial heart tubes as well as their migration and fusion in the midline.

symmetry | Biology, Types, Examples, & Facts | Britannica

Symmetry in animals. Certain animals, particularly most sponges and the ameboid protozoans, lack symmetry, having either an irregular shape different for each individual or else one undergoing constant changes of form.The vast majority of animals, however, exhibit a definite symmetrical form. Four such patterns of symmetry occur among animals: spherical, radial, biradial, and bilateral.
