What are the 5 FUNCTIONS OF MUSCLE TISSUE?
- 1. Producing body movements,Movement of body or parts by skeletal muscle
- 2. Stabilizing body position,Sitting,Standing, Holding head up
- 3. Storing substances within the body-contraction of smooth or skeletal muscle sphincters keeps contents in stomach, parts of intestine, urinary bladder etc.
- 4. Movement of substances within the body
- Heartbeat ,Digestive movements
- 5. Generation of heat (thermogenesis)
- Heat is a by-product of contraction. Used to maintain normal body temp. (85% of all body heat.)
What are the TYPES OF MUSCLE TISSUE? 3 pts
- 1. Skeletal muscle tissue:Skeletal-attached primarily to bones and moves parts of the skeleton
- 2. Cardiac muscle tissue-forms most of the heart, Involuntary-not under conscious control-has a built-in rhythm called autorhythmicity
- 3. Smooth muscle tissue-located in the walls of hollow organs such as BV, stomach, intestine, etc. and also arrector pili muscles.
- Smooth (non-striated)-striations NOT visible under microscope
- Involuntary-NOT under conscious control
What is the ANATOMICAL STRUCTURE OF SKELETAL MUSCLE?
- Skeletal muscles are associated with movements of the body and these movements are the results of the unique characteristics of skeletal muscle cells.
- Skeletal muscles are made up of an orderly arrangement of muscle fiber cells and connective tissues. Within the fascicle, individual muscle fiber cells are surrounded by endomysium.
- Skeletal muscles are composed of a several muscles fiber cells that are wrapped together to form a fascicle.
- (Fascicles are bundles of muscle fiber cells as per above's diagram)
- Fascicles are in turn surrounded by a connective tissue called the perimysium. Bunches of fascicles are then grouped together and covered with the epimysium to form the entire muscle.
- The connective tissues: endomysium, perimysium and epimysium then blend/merge into the tough collagen fibers called tendons, that attaches muscles indirectly to the bone. Not only does the 3 connective tissues attach muscles to bones, they also bind the muscle fibers tissues together and provide strength and support. See diagram below.
What is the THE SLIDING FILAMENT THEORY?
explains that the thick and thin filaments within the sarcomere slide past one another, shortening the entire length of the sarcomere. In order to slide past one another, the myosin heads will interact with the actin filaments and, using ATP, bend to pull past the actin.
What does the AGONIST do?
a contracting muscle whose action is opposed by another muscle.
What does the ANTAGONIST do?
when a muscle or a bone relaxes as the opposite contracts.
What are FAST AND SLOW TWITCH MUSCLE FIBRES?
- Slow-twitch fibers contract slowly and can be used for longer periods of time
- Fast-twitch fibers contract quickly and provide strength and speed, though they also fatigue more quickly
What is CONNECTIVE TISSUE?
Tissue that connects, supports, binds, or separates other tissues or organs, typically having relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, and including cartilaginous, fatty, and elastic tissues
What is FASCIA?
A thin sheath of fibrous tissue enclosing a muscle or other organ
What is Deep Fascia?
Deep fascia is a layer of fascia which can surround individual muscles, and divide groups of muscles into compartments.
What is Muscle Fascia?
