2017 Motor Unit Recruitment and Muscle Fatigue Lab Introduction Human skeletal muscles are made up of hundreds of cylindrically-shaped cells called myofibers‚ and they are bound together by connective tissue. These muscles are stimulated to contract by somatic motor nerves‚ or motor neurons‚ that carry signals in the form of nerve impulses from the brain or spinal cord‚ to the skeletal muscles. Although a motor neuron can innervate several fibers‚ each muscle fiber can only be innervated by one

exercise. Although stretching doesn’t reduce bodily fat nor does it gain muscle; it does set a good foundation for you to perform the necessary activities that lead to good health. With proper flexibility‚ many functions that were previously not achievable can now be done. For instance‚ a tennis game can be fun for a little while. But as your muscle tense up‚ you risk probable sourness and cramping. With good flexibility‚ your muscles stay loose and relaxed and your attitude toward the tennis game and

“Nervous Conditions” by Tsitsi Dangarembga follows a young woman in her journey to find herself and break away from the restrictive culture she was raised in. Even so‚ the young women‚ named Tambu‚ faces challenges because of the strong traditions that are prevalent in her community. Through the struggles of poverty and sexism‚ Tambu manages to still learn a lot about herself and her community. In this book reflection‚ I will be discussing the implications of living in a traditional society as well

Lab IX: Nervous System Histology and Spinal Cord Part II: Neurons and nerve struture 1.) There are three types of neurons. The first is the multipolar‚ which is the most common‚ and they are found as motor neurons and interneurons throughout the central nervous system. The second type of neuron is the unipolar neuron‚ which are also called psuedounipolar neurons. They are found as spinal and cranial sensory neurons. The last neuron is the bipolar neuron. They are only found in olfactory‚ visual

types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal muscle have distinct

MECHANICAL PROPERTIES OF SKELETAL MUSCLE USING FROG GASTROCNEMIUS AIM The purpose of this experiment was to demonstrate the physiological as well as mechanical properties of skeletal muscle using the gastrocnemius muscle of a frog by exploring five different investigations namely the single twitch‚ the graded response‚ the relationship between muscle length and tension‚ muscle tetanus‚ and muscle fatigue. These individual experiments aim to explore the way muscles can contract when an electrical stimulus

Nervous Conditions is a novel by Zimbabwean author Tsitsi Dangarembga‚ first published in the United Kingdom in 1988. The semi-autobiographical novel focuses on the story of a Rhodesian family in post-colonial Rhodesia during the 1960s. It attempts to illustrate the dynamic themes of race‚ class‚ gender‚ and cultural change during the post-colonial conditions of present-day Zimbabwe. The title is taken from the introduction by Jean-Paul Sartre to Frantz Fanon’s The Wretched of the Earth. Plot summary
