MALE REPRODUCTION MALE REPRODUCTIVE PHYSIOLOGY Testis - 2 compartments: interstitial tissue containing the Leydig cells that synthesize and secrete testosterone and the seminiferous tubules that produce spermatozoa and contain Sertoli cells Leydig cells and testosterone synthesis - Leydig cells mainly produce testosterone - T is a prohormone for synthesis of estradiol (vs. aromatase) and DHT (via. 5-alpha-reductase) - many effects of T are mediated via estradiol (esp in

Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS

INTROduction TO THE HUMAN BODY 1. Define anatomy and physiology While anatomy provides us with a static image of the body architecture‚ physiology reveals the body’s dynamic and animated workings. Physiology often focuses on events at the cellular or molecular level. A. Anatomy – studies the structure of the body parts and their relationship to one another. i. Developmental – concerns structural changes that in the body occur throughout the lifespan. Embryology studies the developmental changes

Chameleons Organism Physiology Brianna Kibler October 1‚ 2014 Principles of Biology BIO/101 Matthew Scholten Organism Physiology We know that an organism is anything that is living and can function by itself. This paper will help understand chameleons and how they have evolved to adapt to their surroundings. It will also discuss their physical features inside and out. Myths and facts will be revealed‚ as well as a few comparisons between sexes. Though there are many species of chameleons

consider the system complexity that in many cases is hard to capture. If the system’s simulation is appropriate‚ we can then provide practical feedback to real systems‚ time compression or expansion‚ higher control‚ and lower costs. Thus‚ one question emerges: why is it necessary to simulate traffic (road network)? In order to give an answer to this query we have to keep in mind the system’s complexity. Traffic simulation is necessary because this kind of application domain is inherently complex‚ usually

Organization Structure simulation Organizational structure is the division of labor and the patterns of coordination‚ communication‚ workflow‚ and formal power that guide organizational activities. An organization’s structure reflects the company’s culture and power relationships and can establish new communication patterns and align employee behavior with the company’s mission‚ vision and goals. The organizational structure enables effective communication and smooth workflow‚ but organizational

Ethics Game Simulation The ethics simulation game is a learning tool designed to teach individuals how to make decision between ethical challenges. While one might think making such decisions is an easy task‚ more dilemmas are present than imaginable. The first decision that had to be made was about a product already on the market that was contaminated yet only put a small percentage of users at a low risk. After narrowing the possibilities down to two solutions‚ the choice was made to warn

Benihana Simulation Analysis Harvard Business Publishing has created a computer simulation to replicate the operations management decisions facing Benihana. Benihana is a teppanyaki style restaurant franchise that focuses on bringing a theatrical dinning experience to its patrons. The layout of the restaurant consists of two seating areas: the bar and the dining area. The goal of this simulation is to maximize utilization‚ throughput time and the nightly profit using different batching‚ bar sizing

ANATOMY AND PHYSIOLOGY The pelvis is a large semicircular bone complex that forms the base on which the torso and upper body are positioned. The pelvis‚ which is a rigid and inflexible portion of the skeleton‚ is built to provide a foundation of the movement of other parts of the anatomy‚ particularly the back and the legs. The pelvis also permits the weight of the entire upper body to be evenly distributed
