Joints are where two or more bones meet. They allow the rigid skeleton to move, surrounding soft tissues hold each joint together. Muscles lie over one or more joints at the lower back and extend upwards to the trunk and downwards to the pelvis. At both ends the muscle changes into a tendon by which it attaches itself to different
Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) Tendons bind muscle to bone, and ligaments bind bone to bone. A sprain is an extended and/or torn ligament, the band of connective tissue that connects the end of one bone with another bone. Ligaments support and stabalize the an individuals joints.
9 Go to Ch. 6: The Muscular System in the APR workbook. * Complete the Animations - Skeletal Muscle, Neuromuscular Junction, Sliding Filament, Excitation-Contraction Coupling, and Cross Bridge Cycle and answer the questions on pp. 255–257. Transfer answers to the University of Phoenix Material: The Muscular System Animations document provided on the student website.
Compare and contrast Cardiac and Skeletal Muscle. Discuss how their differences enable them to carry out their function more effectively. Skeletal, cardiac and smooth muscle account for nearly half of our body weight, their roles essential for normal bodily function. Skeletal muscles; attached to the skeleton via tendons; maintain body posture, are voluntary controlled and have antagonistic arrangement for muscular contractions. They tend to enlarge following vigorous exercise, a phenomenon called muscular hypertrophy and are located around the body.
Unit 4222-232Move and position individuals in accordance with their plan of care (HSC 2028) 1.0 Understand anatomy and physiology in relation to moving and positioningindividuals 1.1 Outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals Bones and muscles are concerned with the movement of the body. The skeleton is a rigid framework that gives shape and support to the body and is jointed to permit movement. The vertebral column is the basis of the skeleton and consists of a series of bony rings united by inter-vertebral discs of cartilage. All bones give attachment to muscles, which are responsible for 50% of our body weight and also permit movement. Bones are moved at joints by contraction and relaxation of the muscles attached to them.
HSC 2028 Move and position individuals in accordance with their plan of care 1 Understand anatomy and physiology in relation to moving and positioning individual. 1.1The spinal column is made up of individual bones called vertebrae. In between the bones there are joints that connect these together. A ligament connects bone to support joints. To move a individual incorrectly can cause ligaments to sprain.
Muscular System Overview To complete this worksheet, select: Module: Support and Movement Activity: Anatomy Overviews Title: Muscular System: Overview 1. Click the Skeletal Muscle Cross Section and identify each of the following. Consult your textbook for a description of each. Epimysium the connective tissue that surrounds the entire muscle at the outermost layer of the muscle. Deep Fascia connective tissue with dense irregular tissue that lines the body wall and limbs.
1.) List and briefly explain the meaning of each of the following characteristics of muscle tissue; extensibility, elasticity, excitability, and contractility. Extensibility: The ability for muscle tissue to stretch. Elasticity: The ability of muscle to return to its normal resting size after being stretched. Excitability: The ability of muscle tissue to receive a stimulus from the nervous system.
also called voluntary muscles, are the muscles that attach to bones that we consciously move. 50 Striations-alternating light and dark bands recognizable on skeletal muscles 51 Muscle Sense-the brain's ability to sense where the muscles are and what they are performing during movement 52 Stretch Receptors-work in conjunction with the sensory receptors, also referred to as proprioceptors. Senses the changes in the length of a muscle as it stretches. 53 Origin-end of the skeletal muscle attached to the immovable part of the bone 54 Insertion-end of the muscle attached to the movable part of the bone 55 Prime Mover-a muscle that does most of the work during movement 56 Synergist-muscles that contract and assist the prime mover 57 Antagonists-muscles that resist the prime mover's action and work to cause action in the opposite direction 58 Tendons-composed of parallel fibers kept together by a connective tissue sheath 59 Myosin-thick filament that makes up approximately one half of the proteins that occur in muscle
The Skeletal System Abstract The skeletal system is the foundation of the human body. It consists of different sizes and shapes all of which contributes to the movements of the body. Our bones have multifunctional and life sustaining features which include: protection of the vital organs, stores important minerals, produces red blood cells and provides point of attachment for the muscular system. The skeletal system influences our activities of daily living, everything that we do in a daily basis like bathing, feeding, and functional mobility affects each individuals in order to be productive and most importantly, to survive. Diseases such as Arthritis, affects all across the lifespan.
