of the skeletal‚ muscular‚ and nervous systems involved in the movement you chose in part A. The scent of the hamburger enters the nostril. Upon entry‚ the odor of hamburger encounters the olfactory cilia‚ located in the supporting olfactory epithelium. The cilia pass along the impulse of the odor thru the olfactory cell‚ then further onto the axon bundle‚ before passing through the cribriform plate. Upon leaving that boney structure‚ the signal hops a ride on the olfactory bulb. The bulb in turn

Fantastic Voyage I Brandie Haskins HS130- Unit 4 Kaplan University 03/26/13 Introduction to the voyage Hello everyone! My name is Brandie and today we will be going on a “Fantastic Voyage” through the body of a healthy female who has been feeling under the weather. I was just informed that the female’s body has been invaded by a bacterium that affects the lower right lobe of the lung. I have currently been assigned to pilot the invasion and do a live report on my findings. Before we get

involved. Causes[edit] CSR is a fluid detachment of macula layers from their supporting tissue. This allows choroidal fluid to leak into the subretinal space. The build-up of fluid seems to occur because of small breaks in the retinal pigment epithelium. CSR is sometimes called idiopathic CSR which means that its cause is unknown. Nevertheless‚ stress appears to play an important role. An oft-cited but potentially inaccurate conclusion is that persons in stressful occupations‚ such as airplane

There are three such membranes with each consisting of a simple epithelium supported by loose connective tissue: the pleura lines the pleural cavities and covers the lungs the peritoneum lines the peritoneal cavity and covers the surfaces of enclosed organs such as the liver and stomach the pericardium lines the pericardial
