Eye accessory structures diagram
The eye is made up of three coats, or layers, enclosing various anatomical structures. The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera.The middle layer, known as
the vascular tunic or uvea, consists of the choroid, ciliary body, pigmented epithelium and iris.The innermost is the retina, which gets its oxygenation from the blood vessels of the choroid Continued From Above As the brain stem ascends from the spinal cord, it widens and becomes more
complex in its structures, both internally and externally. An amoeba (/ ə ˈ m iː b ə /; rarely spelled amœba; plural am(o)ebas or am(o)ebae / ə ˈ m iː b i /), often called amoeboid, is a type of cell or unicellular organism which has the
ability to alter its shape, primarily by extending and retracting pseudopods. Amoebas do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms. Human reproductive system, organ system by which humans reproduce and bear live offspring. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are (1) liberation of an ovum, or egg, at a specific time in the reproductive cycle, (2) internal fertilization of the ovum by spermatozoa, or sperm cells, (3) transport of the Pharynx and Larynx. The PHARYNX is a fibromuscular tube which extends from the base of the skull to the lower border of the cricoid cartilage
(at which point it becomes the esophagus). External Brainstem Structures. The brainstem is divided into three regions. The uppermost portion is called the midbrain. It is small. It contains the 3rd and 4th nerve nuclei, the superior and inferior colliculi, and various fiber bundles. Our interactive diagram helps you explore the anatomy of the human brain and learn all about how it functions. Structures of the Shoulder Joint Articulating Surfaces. The shoulder joint is formed by the articulation of the head of the humerus with the glenoid cavity (or fossa) of the scapula.This gives rise to the alternate name for the shoulder joint – the glenohumeral joint. The skull contains all the bones of the head and is a shell for the brain and the origins of the central nervous system. A first glance shows that this is one large
mass of detailed and irregular bone. Upon closer inspection however, it seems that it is intricately constructed of many smaller bone fragment pairs, all unique in shapes and sizes, that bilaterally make up this hollow, three Chlorplasts in the plant cells absorb the light energy and use thisto convert basic products (carbon dioxide and water) into simplesugars through the process of photosynthesis.
