as CO2 levels in blood. Olfaction is the sense of smell. Olfactory sensors are embedded in epithelial tissue at top of nasal cavity (in vertebrates). Axons extend to the olfactory bulb in the brain‚ dendrites end in olfactory hairs on the nasal epithelium. FIGURE 46.3 Olfactory Receptors Communicate Directly with the Brain Odorant—a molecule that binds to an olfactory receptor protein on the cilia of olfactory receptor neurons (ORNs). Olfactory receptor proteins are specific for particular odorants

Ovarian cancer can develop from the epithelial cells surrounding the ovary‚ the germ cells‚ or stromal cells within it. Epithelial ovarian carcinomas account for 85-90% of ovarian cancers‚ and will be the focus of this essay. Most symptoms of epithelial ovarian cancer are due to the fact that it often spreads to the lining of and organs in the abdominal cavity. These symptoms include bloating‚ pelvic or abdominal pain‚ urinary urgency or frequency‚ and trouble eating associated with feeling of fullness

body are connective‚ epithelium‚ muscle and nervous tissue. Connective tissue is an abundant nonliving extracellular matrix‚ located throughout the human body; such as the head‚ tendons‚ bone‚ and many more. It is the most widespread tissue in the human body and is the most durable tissue type. There are so many functions for this tissue‚ that it is difficult to describe just one. However‚ its main function is to support and protect. (Connective tissue‚ 2013) Epithelium tissue lines the body

Anatomy of the maxillary sinus: The maxilla consists of a variety of anatomic structures‚ including the maxillary sinus‚ the lateral nasal walls‚ the pterygoid plates‚ associated vasculature structures‚ and teeth. The maxillary sinus is pyramidal in shape. The base of the pyramid is the medial wall of the sinus that is also the lateral wall of the nasal cavity‚ and its apex is pointed towards the zygomatic bone. The roof of the sinus is also the floor of the orbit. The sinus has a

Digestive system 6.1.1 explain why digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down

level of the pelvic diaphragm. It lies in the anal triangle of perineum in between the right and left ischioanal fossa. The anal canal is divided into three parts. The zona columnaris is the upper half of the canal and is lined by simple columnar epithelium. The lower half of the anal canal‚ below the pectinate line‚ is divided into two zones separated by Hilton ’s white line. The two parts are the zona hemorrhagica and zona cutanea‚ lined by stratified squamous non-keratinized and stratified squamous

structure in the urinary system is the ureters. The ureters are a yellow color found connected to the kidneys and the urinary bladder. The ureters have three layers. The first layer from inside out is the mucosa layer‚ which is composed of transitional epithelium. The second layer is the muscularis layer‚ which is composed of smooth muscle. The third and final layer in the ureters is the adventitia layer‚ which is composed of outer fibrous connective tissue. The next structure in the urinary system is the
