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.
these are bound together by connective tissue. - each muscle fibre is a single muscle cell surrounded by a cell surface membrane. - Inside the muscle fibre is the cytoplasm containing mitochondria and the other organelles found in a cell. - Within each muscle fibre there are also numerous myofibrils, each is composed of repeated contractile units called sarcomeres. - when the muscle contracts the dark band overlaps the intermediate band shortening the length of the muscle
Unit |P2| describe the structure functions of the muscular, skeleton cardiovascular and respiratory system diagrams. Introduction. This essay will present most of the information about skeletal structure, muscle structure, joint structure and everything about human respiratory system. Essay shows complete diagram of human skeleton explaining each and every bone in human body, also its functions. Essay shows the importance of bones in human body and their main role, tasks they accomplish every day.
The response is either increased or decreased contraction of the muscularis. 7. Where are enteric nervous system plexuses located? The myenteric plexus is located between the longitudinal and circular layers of muscle in the tunica muscularis, the submucous plexusis buried in the submucosa. Mastication 8.

Muscle cells contain protein ﬁlaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion. They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.

Study Questions for muscle 1. Long fibers, striated, nucleus is peripherally located (multiple nuclei’s along the fiber) Muscular Fasica = Surrounds the individual muscles and groups of muscles (red, layer 1) Epimysium = Surrounds the muscles (dark blue, layer 2) Perimysium = Surrounds the fasciculi (light blue ring, layer 3) Endomysium = Surrounds the muscle fibers (light blue around orange, layer 4) Aponeurosis: Tendons that are broad and sheet-like 2. A muscle cell is also called a (Muscle Fiber). The plasma membrane of the muscle cell is called a (Sarcolemma). 3.
It's also found in the uterus and fallopian tubes. The movement of cilia move the ovum to the uterus. Glandular Epithelium are basically columnar epithelium with goblet cells. Some parts consist of such a large number of goblet cells that there are only a few normal epithelial cells left. They secrete substances
M.Sc. Bioengineering 2011-2012 Musculosketetal biomechanics assignment ALTOKA ERATO (PAC:11266318) Option V (Kelvin model) The aim of this assignment is to describe the general viscoelastic behaviour of muscles (soft tissues) when they subsist mechanical compression. To achieve that we will use the Kelvin model (standard linear solid model).This model simulates the two different reactions of the muscle,viscous and elastic,respectively by dashpots and springs . To be more precise,it consists of two systems in parallel:a) a spring and b)another spring with a dashpot in series. The spring represents the elastic components of the muscle and obeys Hook’s law : F=k*x but in terms of stress the equation turns into : σ=Ε*ε where σ: applied stress, E:Young's Modulus of the material ε: strain.
