It is composed of several tissues that differ from one another structurally and functionally. The most common forms are listed below. These two components will be the focus of this lab.
Adipocytes may occur in almost any sample of ordinary connective tissue, where they may be found as individual cells or in clumps. Desmosomes connect the plasma membrane to intermediate filaments in the cytoplasm.
It is composed primarily of connective tissue. More at Biochemistry website. These tissues have two principal components, an extracellular matrix and a variety of support cells.
Note the tops of the goblet cells protruding between the cilia. All epithelial cells have six sides but they vary in height. The zona granulosa produces estrogen, whereas the theca interna produces androstenedione that is converted to estrogen by the enzyme aromatase in the granulosa cells.
Uterine structure throughout the menstrual cycle is covered in detail in the next section. Special devices intercellular junctions, tonofilaments provide for structural integrity of the epithelium. The oviducts or fallopian tubes transport the ovum from the ovary to the uterus and serve as the site of fertilization.
Adipocytes are large connective tissue cells which contain a substantial amount of lipid stored in the form of conspicuous round droplets. Organelles and membrane proteins are distributed in different parts of the cell. Macrophages are indistinguishable from fibroblasts, but can be recognized when they internalize large amounts of visible tracer substances like dyes or carbon particles.
This blood is found within the lacunae of the decidua basaliswhich is derived from the stratum functionalis of the endometrium. The pink material in this thumbnail image is extracellular collagen.
Fibroblasts which secrete the fibers and ground substance of the extracellular matrix. Some fibroblasts have a contractile function; these are called myofibroblasts.
With continuing hormonal stimulation, the first meiotic division is completed and a Graafian follicle develops. Other stratified squamous in the body is nonkeratinized. Resting fibroblasts typically have so little cytoplasm that the cells commonly appear, by light microscopy, as "naked" nuclei.This note covers the following topics: Basic Histological Techniques, Epithelial Components, Stratified Epithelia, Connective Tissue, Muscle Tissue, Nerve Tissue, Stains and Staining, Lymphoid Organs, Digestive System - Oral Cavity, Tract and Glands, Respiratory System, Endocrine System, Male Reproductive System and Female.
Epithelium Study Guide. Epithelial tissue comprises one of the four basic tissue kitaharayukio-arioso.com others are connective tissue (support cells, immune cells, blood cells), muscle tissue (contractile cells), and nervous kitaharayukio-arioso.com represent various combinations of these four basic tissue types, which thus comprise the entire body.
Tissue: Tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material. By definition, tissues are absent from unicellular organisms.
Even among the simplest multicellular species, such as.
Loose Connective Tissue. Loose connective tissue is primarily located beneath epithelial membranes and glandular epithelium, binding these epithelia to other tissues, contributing to the formation of organs.
A comprehensive, fun and entertaining site devoted exclusively to histology. Learning histology was never so easy! This site includes histology quizzes, histology games, slides, mnemonics, histology puzzles and tons of information about histology.
One of the best histology sites on the internet! Introduction to tissues (Epithelial, Connective, Muscle and Nervous tissue) A tissue is a group of cells, in close proximity, organized to perform one or more specific functions.
There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and .Download
