- What is the Interrelation of an organism with the environment. A concept of irritants, irritations,biological reaction, excitation, excitability, excitative structuresOrganismal homeostasis depends upon the presence of control systems. Give a physiological example of a negative feedback control system its positive feedback. Clearly describe the role(s) that each of the following elements plays in all control systems: such as controller, effector and receptor.SUBJECT:PURPOSIVE COMMUNICATION Read the following situation and answer the question follow: James Warick, Director of Physical Plant at Southern Hospital, e-mailed Diane curtis, Director of Nursing informing her of a leak in Operating Room 1 that must be shutdown for repairs early next morning. Curtis forwarded the message to Joanne Messing,the operating room nurse supervisor on duty for the night shift. Messing, tired from a long nights work, handwrote a message and taped it on the bulletin board to the nurse supervisor in the day shift to switch the 8am operation from room 1 to room 8 David Swanson, the day shift nurse supervisor, arrived at 7:30 a.m and found Dr.Roberts shouting that his patient was ready for surgery ,but no rooms were available because Dr. Jones had already taken 8 rooms. 1.Enumerate the channels of communication used by each person.? 2.Should different channel of communication have been used instead?why? 3.

- Binding of molecules elicits a conformational change that allows the entry of resulting in the depolarization of the effector cell. O Ach, Cat O2 Ach, Na+ O Ach, Na+ O2 Ach, CatCell to cell communication is one of the four core principles of anatomy and physiology. In order to communicate cells, use: electrical signals chemical signals both are correct neither are correct.Nervous cells use both chemical and electric communication mechanisms, whereas the endocrine system typically uses for communication
- The words for making negative mechanism are; stimuls,integration center, effector, response and receptor_________ controls are inherent to an organ, whereas _________ controls are regulatory mechanisms initiated outside an organ that alter the activity of the organ.Select the statements that correctly describe positive feedback pathways. A sensor/receptor is required to monitor and limit levels. A sensor/receptor is unnecessary to monitor and limit levels.
