Chapter 10 Muscular Tissue. Lecture slides prepared by Curtis DeFriez, Weber State University. Functions of Muscular Tissue. Like nervous tissue, muscles are excitable or "irritable” they have the ability to respond to a stimulus Unlike nerves, however, muscles are also:

1.82 Volts. 0. 1. 2. 3. seconds. 3.44 ms -2. 55 Nm. 406 μ V. The Surface Mechanomyogram (MMG). Mechanomyography (MMG). Non-invasive technique that records and quantifies the oscillations generated by dimensional changes of the active skeletal muscle fibers.

Spinal Control of Movement. Lesson 19. Anatomy. Ventral Spinal Cord Topographic organization Alpha motor neurons Spinal interneurons Striate muscle extrafusal fibers ~. Distal limbs. Proximal limbs. Alpha Motor Neurons. Or lower motor neurons (Class I) Cell body in ventral horn

Muscle Tissue. Chapter 10. Overview of Muscle Tissue. There are three types of muscle tissue Skeletal muscle Cardiac muscle Smooth muscle These muscle tissues differ in the structure of their cells, their body location, their function, and the means by which they are activated to contract.

Spinal Control of Movement . Midterm 2 Results. Types of Muscles. Smooth – digestive tract, arteries Striated: Cardiac – accelerates or slows heart rate Skeletal – moves bones around joints, moves eyes, facial expression, respiration, speech

Exercise Induced Mitochondrial Biogenesis. What is it?. Mitochondrial content is increased in the muscle due to the stress of physical activity Greater volume of mitochondria per muscle fiber Greater ability to synthesize ATP per gram of muscle Improved endurance! Preservation of glycogen

Unit 5 Muscular System Wrap-up. Review of Neuromuscular Junction. Review of Steps of Muscle Contraction Table 8.1 pg. 184. ACH binds to protein receptors Increases permeability to Na + ions which creates a muscle impulse

Therapeutic Massage. Chapter 16. Historical Perspective. Dating back to the ancient Olympians Late 1980’s American Massage Therapy 1992 National Certification Examination for Therapeutic Massage and Bodywork . Purpose. Manipulates the the body’s tissues to: Reduce muscle spasm

Chapter 6 Muscular System. Types of Muscles. Skeletal – striated & voluntary Smooth - involuntary Cardiac – heart Striated means it appears striped. Structure of a Muscle. Muscles are composed of many FIBERS that are arranged in bundles called FASCICLES.

Muscles and Muscle Tissue. Chapter 9. Overview of Muscle Tissue. There are three types of muscle tissue Skeletal muscle Cardiac muscle Smooth muscle

Chapter 9 Muscular System. Three Types of Muscle Tissues. Skeletal Muscle usually attached to bones under conscious control striated. Cardiac Muscle wall of heart not under conscious control striated. Smooth Muscle walls of most viscera, blood vessels, skin

Muscular System. Key Word Parts. My/o-, mys-, and sarco- refer to muscle Spas- (draw, pull), tens- (stretch), -plegia (paralysis), therap- (treatment), therm- (heat), dynam- (power) . Functions. The human body has more than 600 muscles The functions of the muscular system Movement

Muscular System. Honors Anatomy & Physiology. Skeletal, Smooth, or Cardiac?. SKELETAL Striated Voluntary Multinucleated Bound to bones to move skeleton. SMOOTH Not striated Involuntary Single nucleus In hollow organs like stomach Moves food. CARDIAC Striated Involuntary

Muscle Physiology:. Muscular System Functions. Body movement Maintenance of posture Respiration Production of body heat Communication Constriction of organs and vessels Heart beat. Properties of Muscle. Contractility Ability of a muscle to shorten with force Excitability

Muscle: Contractions and Neural Control. More than ___ muscles in the animal body Characteristics of muscle dictate its function Mammalian and avian – long, unbranched, and threadlike that taper at both ends Muscle Fiber = ___________________. Function. Movement of skeleton

Muscular System. Muscles for Locomotion. Engage. Tennis Ball Muscle Activity. Explore. Chicken Wing Dissection

The Muscular System. Functions of Muscle Tissue. Movement Facilitation Thermogenesis Postural Support Regulation of Organ Volume Pumps Blood (HEART). Characteristics of Muscle Tissue. Contractility ability to become short and thick while producing movement.
