WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. The term anatomy refers to the structure and relationship of body parts such as tissues and organs. Physiology on the other hand is how these structures work as in individual and in the body as a whole. Take the circulatory system for example. The heart itself‚ blood vessels and blood

The patient is a 27 year old female‚ vital signs are normal‚ lab values are WNL. Normal is a very subjective term. It can have many different meanings to many different people. In nursing‚ normal can often be described in terms of homeostasis. Homeostasis is a concept that was first conceived by Claude Bernard‚ a 20th century physiologist. Walter Canon‚ a physician in the 20th century expounded upon this concept‚ using feedback mechanisms to explain Bernard’s concept’s regulation. These

students human anatomy and physiology. Physiology is the study of the process or function of living things. The major goals of physiology are to understand the response of the body to stimuli and understand how the body maintains conditions within homeostasis in various environmental conditions. The study of physiology consists of many different levels including cell physiology‚ organ physiology and systemic physiology. Students will be exposed to all of these levels starting at the cellular level and

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture

contributes to muscle loss‚ weakness‚ and finally to death (Sandri). 6. These findings will help to define the role of the lysosomal system in muscle homeostasis during physiological or pathological conditions (Sandri). 7. Lysosomes control the half-life of long-lived proteins and the turnover of organelles and therefore‚ are critical for cellular homeostasis (Sandri). 8. Skeletal muscle contraction is a potential source of metabolic‚ mechanical‚ and thermal stressors. Therefore‚ the quality control of

from the nervous system as well as by chemical receptors in the blood and hormones produced by other glands. By regulating the functions of organs in the body‚ these glands help to maintain the body’s homeostasis. Cellular metabolism‚ reproduction‚ sexual development‚ sugar and mineral homeostasis‚ heart rate‚ and digestion are the few among them that are regulated by the actions of hormones. The reason why the endocrine system is important is because it influences almost every cell‚ organ‚ and

is increasing‚ and increasing is positive feedback. 13a. A positive feedback loop would be helpful in maintaining homeostasis because it keeps the body at a stable state for example if you were to have breathing‚ you would need and receive positive feedback in order to receive oxygen and not pass out. 13b. A single negative feedback loop would be helpful in maintaining homeostasis because it keeps the body at a stable state for example if you are too hot you would get negative feedback. 14. According

This is called homeostasis. These conditions include water content‚ ion content‚ body temperature and blood glucose concentration.
