NAME __Molly Manning__ LAB TIME/DATE ___10/24/13__ Exercise 2 Skeletal Muscle Physiology The Muscle Twitch and the Latent Period 1. Define the terms skeletal muscle fiber‚ motor unit‚ skeletal muscle twitch‚ electrical stimulus‚ and latent period. Skeletal muscle fiber-fibers attached to the skeleton that produce muscle tension. Motor unit-consists of the motor neuron and all of the muscle fibers. Skeletal muscle twitch-mechanical response to a single action potential. Electrical stimulus-muscle

BSC2085 Anatomy-Physiology 1 Exam 2 Study Guide‚ Chapters 5 & 6 There are only four primary tissue types found in adult organs; epithelial‚ connective‚ nervous‚ and muscular tissue. Epithelial tissue lines body cavities‚ covers the body surface‚ and forms the lining of many organs. Connective tissue serves in most cases to bind organs to each other. Nervous tissue and muscular tissue are considered excitable tissues because they are very sensitive to outside stimuli. A simple epithelium consists

Anatomy of the Future Andreas Vesalius August 1‚ 1539 After attending college at the University of Louvain‚ I moved to Padua to study for my doctorate. After being offered the chair of surgery and anatomy‚ I pursued my desire to research the anatomy. Although surgery and anatomy are considered of little importance in comparison to other branches of medicine‚ I believe that surgery must be grounded in anatomy. I have been given the opportunity to perform my research on the cadavers of executed

Did you get it? 1. What’s the role of eyelids? To protect the eyes. 2. Which structure of eye forms tears? Lacrimal glands 3. What are tears? A dilute saline solution containing lysozyme and antibodies. 4. What’s the visual role of the external eye muscles? They direct the eyeball toward what you wish to see. 5. What is the meaning of the term blind spot in relation to the eye? The blind spot contains no photoreceptors; it is the site where the optic nerve leaves the eyeball 6. What function

Chaper 11 1. Define responsiveness‚ conductivity‚ contractility‚ extensibility‚ and elasticity. State why each of these properties is necessary for muscle function. a. Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces
