The Bladder (Human Anatomy): Function, Picture, Location, Definition
Bed-wetting (nocturnal enuresis): Bed-wetting is defined as a child age 5 or older who wets the bed at least one or two times a week over at least three months. Dysuria (painful urination): Pain or discomfort during urination due to infection, irritation, or inflammation of the bladder, urethra, or external genitals
The Human Body System
Conducting zone, respiratory zone Allow gas exchange to take place in order to remove CO2 from the blood Central nervous system, peripheral nervous system Receive information, process the information, respond to the information Kidneys, liver, sweat glands, lungs, large intestines Expel metabolic wastes from the body, maintain internal balance Endocrine glands, hormones Control and regulation of body processes Internal and external structures Production of human sex cells, release of sex hormones 189. PERIPHERAL NERVOUS SYSTEM: Spinal Nerves Spinal nerves refer to nerves which carries motor, sensory, and autonomic signals between the spinal cord and the body
THE CONNECTIVE TISSUES
Tissues and organs subject to expansive forces contain elastic fibers, such as, the walls of arteries, the vocal cords, skin, the trachea and the bronchi. The tough, inelastic tendonous sheets and cords formed by tendons provide great resistence to pulling forces, e.g., a pencil thick tendon has been found to support up to 1000 pounds
PICTURE endosymbiosis Theory that attempts to explain the origin of the DNA-containing mitochondria and chloroplasts in early eukaryotes by the engulfing of various types of bacteria that were not digested but became permanent additions to the ancestral "eukaryote". epithelial tissue Cells in animals that are closely packed in either single or multiple layers, and which cover both internal and external surfaces of the animal body
Cell Death and Disease - Autophagy and mitochondrial alterations in human retinal pigment epithelial cells induced by ethanol: implications of 4-hydroxy-nonenal
TUNEL analysis revealed an increase in the number of cell death in EtOH groups treated with 3-MA (Figure 3k), more than twofold compared with EtOH groups alone. Our results are in agreement with previous works reporting that EtOH increases autophagy flux in liver and brain cells.14, 15EtOH exposure induces mitochondrial fragmentation and promotes mitophagyThe negative effects of EtOH on hepatic44, 45, 46 and neuronal47 mitochondria are well documented
There are three types of muscle: skeletal muscle which is connected to bone and helps with voluntary movement, smooth muscle which is found inside organs and helps to move substances through organs, and cardiac muscle which is found in the heart and helps pump blood. Each day, the kidneys process about 200 quarts (50 gallons) of blood to filter out about 2 quarst of waste and water Adults excrete about a quarter and a half (1.42 liters) of urine each day
When the bladder is empty, the outermost cells are polygonal or dome-shaped, but when the bladder is full (distended), the thickness of the epithelial layer is less and the outermost cells appear more squamous. 7) Transitional Transitional epithelia is a special type of epithelia restricted to the excretory passages of the urinary system (renal pelvis, most of the urethra and urinary bladder)
What are Epithelial Cells? (with pictures)
These alone would have been enough for a diagnosis of a urinary tract infection, but because I also have a kidney disease, my doctor wanted to do a urinalysis to make sure the infection had not reached my kidneys. by email wiseGEEK Slideshows Adorable animal families that will make you "aww" You won't believe these 10 facts about people Top 10 unbelievable historical concurrencies Top 10 facts about the world Can you see through these real-life optical illusions? 10 most extreme places on Earth These 10 animal facts will amaze you These 10 facts about space will blow your mind 10 hilariously insightful foreign words Top 10 amazing movie makeup transformations Epithelial cells are a group of tightly compressed cells that layers itself on the internal and external surfaces of bodily organs and other surfaces found in the body
Mixed Human Body Trivia - Fun Facts and Information
What other system is it part of? In the male testes, there are cells that are nicknamed, "nurse cells." What are these cells really called? What system does verucca vulgaris occur in? After strenuous cardiovascular exercise, which part of the nervous system is responsible for slowing down heart rate? In the kidney there is a microscopic structure which functions to collect the blood filtrate that will eventually form urine. Which organ is the only one listed which contains this type of cell lining? What is a horseshoe kidney? What is the primary function of the colon? The tongue is part of the digestive system
Recently, studies looking at the regulation of genes downstream of Pax6 in the Pax6 heterozygous mouse, suggests the pathogenesis of ARK is due a number of mechanisms and not solely due to LESC deficiency (Ramaesh et al., 2005). Aniridia represents a spectrum of disease, with iris anatomy defects ranging from the total absence of the iris to mild stomal hypoplasia with a pupil of normal appearance
Tissue: The Living Fabric
Covering and Lining Membranes Cutaneous membrane, or skin, is an organ system consisting of a keratinized squamous epithelium firmly attached to a thick layer of dense irregular connective tissue . Stratified squamous epithelium is composed of several layers with the cells on the free surface being squamous-shaped and the underlying cells being cuboidal or columnar in shape
These cells show the irregular, flat shape characteristic of typical "squamous cells." The nucleus (A) is centrally located, the cell membrane (C) is very thin, and the cell is filled with cytoplasm (B). The bracket labeled A marks the stratified squamous epithelium.The many layers of cells that make up this tissue are easily seen with higher magnification (right)
