In molecular biology, an axoneme, also called an axial filament, is the microtubule-based cytoskeletal structure that forms the core of a cilium or flagellum. [ 1 ] [ 2 ] Cilia and flagella are found on many cells , organisms , and microorganisms , to provide motility.
Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
For example, bending the elbow, or clenching a hand into a fist, are examples of flexion. When a person is sitting down, the knees are flexed. When a person is sitting down, the knees are flexed. When a joint can move forward and backward, such as the neck and trunk, flexion is movement in the anterior direction. [ 10 ]
Anatomy is often described in planes, referring to two-dimensional sections of the body. A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through the body. Three planes are commonly referred to in anatomy and medicine: [1] [2]: 4
In human anatomy, the anatomical planes are defined in reference to a body in the upright or standing orientation. A transverse plane (also known as axial or horizontal plane ) is parallel to the ground; it separates the superior from the inferior , or the head from the feet.
The thicker the membrane, the more each face must deform to accommodate a given curvature (see bending moment). Many of the values for K a in literature have actually been calculated from experimentally measured values of K b and t. This relation holds only for small deformations, but this is generally a good approximation as most lipid ...
Miami being in the US is a big factor, as it is the top market for the Italian luxury automaker, with Florida the second-biggest market for Lamborghini in the country, following California.
If clockwise bending moments are taken as negative, then a negative bending moment within an element will cause "hogging", and a positive moment will cause "sagging". It is therefore clear that a point of zero bending moment within a beam is a point of contraflexure—that is, the point of transition from hogging to sagging or vice versa.
