Morphology of a male skeleton shrimp, Caprella mutica Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1]This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of internal parts like bones and organs, i.e. internal ...

Motion, the process of movement, is described using specific anatomical terms.Motion includes movement of organs, joints, limbs, and specific sections of the body.The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved.
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.
Definition Etymologic memory aid; apophysis: Any of various processes or protuberances on a bone. apo-+ physis, "outward from the growth part; outgrowth" diaphysis: The long, relatively straight main body of a long bone; region of primary ossification. Also known as the shaft. dia-+ physis, "between the growth parts" epiphysis
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
The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward. The articular surfaces are coated with hyaline cartilage. In the cervical vertebral column, the articular processes collectively form the articular pillars. These are the bony surfaces ...
The standard anatomical position, or standard anatomical model, is the scientifically agreed upon reference position for anatomical location terms.Standard anatomical positions are used to standardise the position of appendages of animals with respect to the main body of the organism.
