Homo sapiens diseases - Cutaneous apparatus and subcutaneous tissue
disseminated superficial actinic porokeratosis : an autosomal dominant skin disorder occurring on sun-exposed skin in individuals over 16 years of age, especially in females, and characterized by the presence of numerous superficial, annular, keratotic, brownish red macules, the centers of which become depressed and the borders form a sharp ridge. The occurrence of Gram-negative folliculitis should be considered in acne patients in whom oral treatment with tetracyclines has not resulted in a significant improvement of acne lesions after 3-6 months' treatment
unblinded search for term A process where the participant, healthcare provider, or person assessing the outcomes knows which intervention the participant is receiving. Because of this, cognitive screening tests can falsely indicate dementia in people with lower education, culturally and linguistically diverse backgrounds, and lower intelligence
The tail is used for balance and support, particularly when the animal is sitting erect and using the forelimbs in a manner more or less similar to the way the arms are used by humans. Diaphragm - Notice that the lungs are located within closed cavities, the thoracic or pleural cavities, which are lined by membranes, called the pleura
Flashcards - Chapter 4 Tissue: The Living Fabric (TB)
A) embryonic B) dense regular C) areolar D) reticular A) embryonic(this multiple choice question has been scrambled) The shock-absorbing pads between the vertebrae are formed of fibrocartilage. A) Stratified epithelia are present where protection from abrasion is important.(this multiple choice question has been scrambled) Select the correct statement regarding adipose tissue
The diaphysis in long bones has a large medullary cavity, whereas the epiphyses do not.93Describe how oxygen is carried from outside a bone to an individual osteocyte.Blood vessels enter through the periosteum into a perforating canal. The parents were told to increase her intake of calcium and vitamin D and to make sure that she gets some sunshine every day.98Clinical Questions Emily, a 64-year-old obese woman, was brought to the hospital suffering pain in her legs, and an X ray revealed that she had a simple fracture in her right femur and a crack in her left tibia
In fact the so-called annular ligament does not exist; it is an integrated part of the aponeurotic layer of connective tissue via which supinator muscle fibers insert to the lateral epicondyle. The patterns of distribution and orientation in such zones are understandable from the perspective of the architecture of the muscular tissue related to the connective tissue architecture
Visual Histology - Histology Text Atlas Book - 303-485-9110
Within a given reticular Fiber, the Collagen fibrils that compose its core are covered by a Glycoprotein coat that resembles material of the Basement Membrane. A cell that can adopt many shapes, depending on its activity, the Fibroblast produces the two major classes of extracellular material found in connective tissue: fibers and Ground Substance
Blue Histology - Connective Tissues
For example, in the palms of the hands, on the plantar surface (sole) of the feet and in the gluteal region (buttocks) it has a structural, cushioning function. Elastic fibres Elastic fibres are coloured in fresh tissues - they are light yellow - but this colouration is only visible if large amounts of elastic fibres are present in the tissue, for example, in the elastic ligaments of the vertebral column
What are the differences between collagen and reticular fibers? (See lecture notes.) Do all tissues associated with reticular fibers constitute a reticular connective tissue? C. CELLS OF THE CONNECTIVE TISSUE PROPER SOURCE OF CELLS CELL TYPES MOTI- LITY NUCLEUS CYTOPLASM FUNCTION Mesenchymal cell of the embryo or those persisting in the adult
Tissue - definition of tissue by Medical dictionary
This term is especially used in relation to muscles, tendons, ligaments, skin, fat, and other connective tissues that are occasionally the source of pain when they are injured. brown adipose tissue a thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including humans; it is prominent in the newborn
Lab 2. Connective Tissue
What is the pink-staining material which is interspersed within the reticular framework? Note the variations in the architecture of reticular fibers which you will come to understand later on. You may not be able to discern the difference between chondrocytes and fibroblasts by nuclear shape, but if a lacuna surrounds the cell, it is a chondrocyte; if not, a fibroblast
CONNECTIVE TISSUE
Their main function is to plug (patch) small breaks in blood vessels and prevent bleeding (hemorrhage); they adhere to connective tissue exposed at the damaged site and initiate clot formation. Acute inflammatory responses in loose connective tissue are characterized by changes in blood vessel permeability, migration of cells involved in clearing debris as well as by healing or walling off the damaged area
Connective Tissue
The small blood vessels (capillaries) are the size of collagen fibers, but may be distinguished from the latter by the presence of thin nuclei (of endothelial cells) oriented parallel to the axis of the capillary. Reticular C.T., containing a 3-dimensional network of reticular fibers, make up the stroma of lymphatic and hemopoietic tissues such as lymph nodes, thymus, spleen and bone marrow
