Mammal Cerebellum – cerebellum coordinates muscular activity, maintains posture and equilibrium. The cerebellar cortex forms a series of deeply convoluted folds or folia supported by branching central medulla of white matter. Molecular layer – contains two main types of neurons: stellate cells and basket cells, w/c are scattered among dendritic…[Read more]

Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells. These cuboidal cells have large, spherical and central nuclei. Simple cuboidal epithelia are found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, and parts of the eye and thyroid. On these surfaces,…[Read more]

Stratified squamous keratinized epithelium is found mainly in the epidermis of our skin. It helps prevent water loss or dehydration, and protection from external forces. The cells in the basement membrane move progressively toward the surface of the skin as they accumulate keratin (through keratinization). They become thinner as they approach the…[Read more]

This is an example of a Skeletal muscle (longitudinal section) viewed under HPO magnification… The numbered parts are: 1. MUSCLE FIBERS = Fibers are packed into regular parallel bundles. Long and cylindrical in shape. 2. NUCLEI = Muscle cells and muscle fibers have many nuclei because these cells arise from a fusion of myoblasts. 3. STRIATIONS =…[Read more]

1.Cilia – found in the lungs, respiratory tract and middle ear. It has a rythmic waving or beating motion. Cilia keeps the airways clear of mucus and dirt, allowing us to breathe easily without irritation. 2. Goblet cells – secrete mucus in order to protect the mucous membrane where they are found, they accomplish by secreting mucins, large…[Read more]
