An indication that Lucas has an ear infection is that he’s not sleeping well, he hardly eats, and constantly pulling his ear. In children it might be harder to conclude what these symptoms can be exactly since they don’t really speak clearly to actually express what’s bothering them. Chronic otitis media is an inflammation or infection that lies behind the eardrum, it appears and disappears that’s why it’s considered chronic. Some symptoms of otitis media are: sleeplessness, ear pain which…

Kaylina “Wally” Nies ANT4525L - Killgrove December 3, 2014 Skeletal Report Many of the medical skeletons that are used for analysis in ANT4525L: Human Osteology come from the Middle East region. They range in how old the bodies were at death to how old they have been deceased and skeletonized. Upon first displaying medical skeleton number four in anatomical order, it was clear that this skeleton was in a better condition than the other skeletons that were assigned. The body had a whiter tint to…

which consists of the dorsal shield (aboral side) and oral shield (oral side.) Unlike sea stars in class Asteroidea, spiny brittle stars have unbranched arms that are setting off from the central disk. Each arm is covered with large, well-developed ossicles called spines—spines are made up of calcium…

LIMBIC SYSTEM AND TINNITUS Introduction A human body is a very delicate and complicated group of systems and organs that work together. We can say that each part of the body is controlled by and connected to several many organs. Thus, many diseases and disorders in one organ can actually indicate the error in completely different organ or system. That brings us to this, The limbic system and Tinnitus. A person who has tinnitus is a person who is continuously hear noisy and annoying voices and…

around to also vibrate creating sound waves that radiate outwards from the main source. The sound reaches the ear pinna to then send the vibrations down the ear canal and onto the eardrum. This creates vibrations on the Ossicles (malleus incus and stapes). The vibration triggers the ossicles to vibrate…

Hearing and Balance (worth 15 points total) Label the parts of the ear in the picture. The choices are ear canal, oval window, cochlea, pinna, tympanic membrane, ear ossicles, cochlear nerve, semicircular canals, and Eustachian tube. (1) Pinna (2) Ear Canal (3) Tympanic Membrane (4) Cochlear Nerve (5) Oval Window (6) Cochlea (7) Ear Ossicles (8) SemiCircular Canals (9) Eustachian Tube Test your sense of…

waves into vibrations. It can do this because of the eardrum, which is a tight flap of skin that vibrates when it is hit by sound, just like a drum. The eardrum is the part of the ear that separates the outer ear from the inner ear and contains the ossicles, which are the three smallest most fragile bones in a person’s body.…

can be divided along central axis). Echinoderms are also triploblastic and coelomate. Instead of being protostomes, the blastopore develop into the anuss, making them deuterostomes. Classes in this phylum are characterized by their arrangement of ossicles, which are hard calcium plates. Part of the body cavity transforms into a water vascular system, a water powered system. Some echinoderms, like sea stars, have arms which contain tube feet. Tube feet help echinoderms by aiding in locomotion and…

EAR INFECTIONS Infections of the ear are the most prevalent diagnosed disease among children in the United States. When talking about child’s safety, it’s their health that counts most due to their numerous exposures to the environment harboring germs and the likes. Ensuring that we care for our children’s ear is very vital not just on looks in their physical composure but also the well-being attributed to their language improvements, academic excellence among other. The nature by which the…

where to go and therefore circulate in the ear canal layering on top of one another causing an increase in their amplitude. They then bounce back through the system, back toward the cochlea at which time the sound waves are further amplified by the ossicles as they finally pass to the cochlea where they are now more easily perceived. The frequencies most affected by the occlusion effect are the lower frequencies (Katz, 2015, pg. 51). 2.…
