Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) --The difference between a tendon and a ligament is that a tendon attaches to muscle. (ie. muscle-bone‚ muscle-muscle‚ muscle- skin) A ligament‚ however‚ attaches to cartilage. (ie. cartilage-bone‚ cartilage-cartilage‚ bone-bone) 2. What bones form the articulation (joint) of the ankle? Did Jill most likely sprain or strain her ankle? Explain your

Enlist its advantages? 1+1 marks b). briefly mention the three determinants of resting membrane potential. 3 marks Ans: Q.1.a. SATTATORY CONDUCTION: 1 mark Propagation of action potential along a myelinated nerve fiber from one node of Ranvier to other in jumping manner is called as saltatory conduction. r Node to node conduction

trend toward bilateral symmetry and cephalization * Invertebrate Nervous Organization * In simple animals‚ such as sponges‚ the most common observable response is closure of the osculum (central opening) * Hydras (cnidarians) have a nerve net that is composed of neurons * Planarians‚ (flatworms) have a ladderlike nervous system * In annelids (earthworm)‚ arthropods (crab)‚ and molluscs (squid) the nervous system shows further advances * Cephalization - concentration

Absolute Threshold and Differential Threshold Our five physiological senses have unknowingly fooled us – on a regular basis‚ no less – to the benefit of marketers and manufacturers. By exploring the psychological and physiological concepts of human perception‚ companies are discerning the differences of absolute and differential thresholds and applying it to marketing their products and effectively influencing consumer’s buying decisions. Once a product’s thresholds are distinguished‚ companies

4: Generation of Action Potentials Name: Instructor: Date: PREDICTIONS 1. Exceeding the threshold depolarization at the trigger zone DECREASES the likelihood of generation of action potential. 2. Action potential amplitude: DOES NOT CHANGE with distance 3. Increasing frequency of stimulation to the trigger zone: DOES NOT increase the production of action potentials. MATERIALS AND METHODS Experiment 1: Effect of Stimulus Strength on Action Potential Generation 1. Dependent Variable

Dread Poets Society (BBC2) co-written with the poet Benjamin Zephaniah. For ten years he also wrote a weekly column for the Saturday Guardian‚ eventually called Staffordshire Bull. The text under analysis called “Tinkling the ivories‚ jangling the nerves” tells us about the author’s recommendations concerning the choice of a musical instrument to learn. He examined the most popular musical instruments and gave a funny characteristic for each of them. It should be mentioned that the text draws the

The Nervous System: Ion Channels 1. What structures in the cell membrane function as ion channels? Intergral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? a. Charge on ion (+ or -) b.Size c. The amount of water the Ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an non-gated channel. 4. Would

Science Independent Project taste threshold Practical Report hYphothesis The lesser the concentration of the solution‚ the lighter its taste become. The result will be subjective. Aim The aim is to determine an accurate common threshold of taste for sweetness‚ sourness and saltiness by determine what is the lowest concentration of a solution that still has perceptible taste for salt‚ sugar and vinegar.
