A tendon is tissue that connects muscles to bones. It is the muscles job to move the skeletal structure of the body. When a muscle contracts it creates a pulling motion. It is the connection of the tendon that acts as an elastic band, this allowes a contraction to move the bones. What is a ligament made of?
Section 17.3- The muscular system makes movement possible Vocabulary 1. Muscular system- The muscles of the body that together with the skeletal system, function to produce movement 2. Skeletal muscle – A muscle that attaches to the skeleton 3. Voluntary muscle- A muscle that can be moved at will 4. Smooth muscle- Muscle that performs involuntary movement and is found inside certain organs such as the stomach 5.
Elasticity; The ability to be able to return to normal shape. While contraction is taking place the muscular system performs 3 functions; Motion, Heat Production and Maintenance of posture. Motion; The ability of being able to move e.g. walking or running. However, with motion you must know about levers.
[TYPE THE COMPANY NAME] DIFFERENCE BETWEEN THREE MUSCLE TYPES SKELETOL, SMOOTH AND CARDIAC MUSCLE ... GAOLATLHE THABISO KWENAMORE 24 SEPTEMBER 201101827 BIO 231 INTRODUCTION Muscles are multicellular contractile units. They are divided into three types which are skeletal muscle, smooth muscle and cardiac muscle and classification is done according to their structure, location and their function (Tortora and Derrickson,2011). Skeletal muscle is mainly responsible for the movement of the skeleton, but is also found in organs such as the globe of the eye and the tongue. It is a voluntary muscle, and therefore under conscious control, skeletal muscle is specialized for rapid and forceful contraction of short duration (Bevan et al,1996). In describing the cellular components of skeletal muscle, several specialized terms are used such as the plasma membrane of skeletal muscle is called the sarcolemma; its cytoplasm is known as sarcoplasm; the endoplasmic reticulum is called the sarcoplasmic reticulum.
It comes from the muscle tension which is produced during muscle contraction. A force internal to the human system is the outcome, which produces tension on the skeletal system, resulting in an angular motion about the joint. An example of a biomechanical technique is a resolution of force or a vector resolution. It provides a way to establish the two component forces directly associated with a net force. The net force is what makes the movement happen and is called the resultant force.
The following graph illustrates the relationship between Maximum weight held at it’s related angle in upright and horizontal positions. It can be seen from the graph that both positions follow the same trend between maximum weight and its angle. As the angle increases, greater weight can be held. However, the value of the weights are greater in body its upright position. Experiment 2: To explore the force-velocity relationship, experiment 2 was conducted in two parts: In part A this relationship was investigated during maximal muscle contractions and in part B it was observed during a multi-joint and multi muscle activity while exercising on a wattbike.
The nerve conduction velocity is determined by recording the motor response of a muscle to the stimulation of its motor nerve at two or more points along the nerve course. The time between stimulation and response is measured and compared to the distance between the point of stimulation and point of response. Precise parameters of measurement have been developed for the ulnar nerve and the motor response is measured over the abductor digiti minimi. The ulnar nerve comes from the medial cord of the brachial plexus, and runs inferior on the medial/posterior aspect of the
Brock Perry HPE295 Grier Gatlin Muscle Fibers Our body is composed of many different groups of muscles and each person has a unique composition of muscle tissue in their body. Different types of athletes usually have one predominant type of muscle fiber, that being the kind that suits their sport the best. Each one has it's own characteristics and is suited to a particular type of movement. Another way to classify these fiber types is by their contractile and metabolic properties, thereby dividing them into slow and fast twitch fibers. The first type of fiber we will look at is the type I, or slow twitch fibers.
Myofibrils are composed of smaller filaments. Identify each of these structures in the diagram. Actin Filaments Muscle fiber Myosin Filaments Titan Filaments Terminal cisterns of SR Mitochondria Sarcoplasmic Reticulum () Sarcolemma Myofibrils Sarcomere Sarcoplasm T (transverse) tubules Describe what happens when a sarcomere shortens. The shortening of a sarcomere causes the shortening of the whole muscle fiber, which in turn leads to shortening of the entire muscle. Identify each of the following: Origins of triceps brachii Belly of triceps brachii Insertion of triceps brachii humerus 4.
While the SNS directs the movements of the skeletal muscles, the ANS regulates involuntary processes such as the heart beating, breathing, blood pressure, and blood sugar level. When compared to other animals’ brains, the human brain is a more complex central nervous system. The reason for this is due to the proficiency of the human brain to continuously develop both in the structure and function of numerous cells in it as a responsive mechanism towards new incoming information, experiences, and even shock, which is also known as brain plasticity.
