ACTIVITY 6: The Skeletal Muscle Length-Tension Relationship 33. In a force-length graph‚ a. the muscle length is the independent variable. b. the amount of force generated is the dependent variable. c. both active and passive forces must be considered. d. All the above are correct. correct answer 34. According to your lab manual‚ the protein titin is the primary cause of _________ __________. Passive Force 35.

LABORATORY REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force

Often we see that having eyestrain is just the beginning. Whenever you don’t see well other factors will play into it‚ like headaches‚ soreness‚ and fatigue. After working out though‚ we often have lactic acid buildup‚ which will cause fatigue and muscle weakness‚ so we must rule that out. 3. Why is Annie having problems breathing? Breathing is an involuntary function of the respiratory system. In the spinal cord there are nerves that are in charge of these involuntary functions. The apneustic

ability to estimate weight of an object‚ the force and time at which our muscles must be contracted are examples of our proprioceptive ability. Examples of proprioceptors are muscle spindles also called stretch receptors and their associated 1a axons. These receptors make up the somatic sensory system that is focus on body sense or proprioception. The muscle spindle consists of several types of speacialized skeletal muscle fibers that are contained within a fibrous capsule. In the middle region

the way in which muscles‚ tendons‚ the skeleton and ligaments interact to enable movement including antagonistic muscle pairs‚ extensors and flexors. Cartilage: a tissue made from collagen‚ which protects bone ends A muscle: an organ that produces movement by contraction A joint: the junction between two bones A tendon: joins muscle to bone A ligament: joins bone to bone to stabilise a joint Muscles work in pairs. One muscle produces the opposite movement from the other muscle‚ therefore‚ the

length-tension relationships represent an important part in the function of skeletal muscle. When skeletal muscle is stimulated‚ passive tissue rapidly changes into dynamic tissue which can produce force. Furthermore‚ during this process‚ the length of muscle may decrease‚ increase‚ or remain the same. Moreover‚ the amount of power a muscle can produce depends on its length‚ velocity and stimulation Powers & Howley (2015). Muscle velocity and stimulation are normally in a constant when creating a length-tension

Title: Grip Strength and Muscle Fatigue I. Purpose/Hypothesis: In this lab the subject will grip on a scale that measures the amount of force being put on it. We will observe the change in hand strength during continuous grip over time. Then we will also measure hand strength during rapid‚ repetitive gripping. I believe that hand strength will weaken during a continuous grip more than if you were to keep a repetitive grip. II. Procedure: 1. Connect the Hand Dynamomenter to LabQuest and select
