their wheels‚” and the twnaion in the muscle keeps increasing. 9. Muscle tone is a state of continuous partial contractions. Muscle tone is the result of different motor units‚ which are scattered through the muscle‚ being stimulated by the nervous system in a systematic way. If the nerve supply to a muscle is n longer stimulated in this manner‚ and it loses tone and becomes paralyzed. Soon After‚ it becomes flaccid‚ or soft and flabby‚ and begins to atrophy. 10. One of these points‚ the origin

Comparative Anatomy Investigation Aim: To create a scientific comparison between the Integumentary and Digestive systems between a mammal (i.e. Rat) and an amphibian (i.e. Toad). A dissection of both a rat and a toad had been completed to make a comparison between an amphibian and a mammal. In specific the Integumentary system and the Digestive system were closely observed and studied. This comparison will first investigate the Integumentary system and all similarities and differences the

The Anatomy and Physiology of Cystic Fibrosis Samantha J. Cordova Pueblo Community College Abstract The main topic researched in this paper is cystic fibrosis. The research in detail is that cystic fibrosis is classified as a genetic disorder and in what ways this disorder affects the gene expressions. More facts found in this paper will be who can get cystic fibrosis‚ which organs are mostly affected‚ and what specifically causes the problems found from cystic fibrosis. Common symptoms

Chapter 5 The skin is composed of two distinct regions‚ the epidermis and the dermis. These two areas are firmly attached to one another along a wavy borderline. The epidermis (epi = upon) composed of epithelial cells‚ and is the outermost protective shield of the body. Epidermis - Structurally‚ the epidermis is a thick keratinued stratified squamous epithelium consisting of four distinct cell types and five distinct layers. Cells of the Epidermis - Cells populating the epidermis include: keratinocytes
