Chapter 9: Muscular System Lecture #1

What is Moebius syndrome? Absence of the sixth and seventh cranial nerves which carry impulses from the brain to the muscles of the face Symptoms? difficulty: sucking swallowing squinting eyes moving tongue smiling

Absence of the sixth and seventh cranial nerves which carry impulses from the brain to the muscles of the face

Symptoms?

What treatment did Chelsey Thomas receive? Underwent two ‘smile’ surgeries At 7yo, transplant of nerve and muscle tissue from legs to either side of her mouth

3 Types of Muscle Tissue Skeletal Muscle Tissue Cardiac Muscle Tissue Smooth Muscle Tissue

Cardiac Muscle Tissue

Smooth Muscle Tissue

Skeletal Muscle Tissue Tissues you’ll find in skeletal muscle Skeletal Muscle Tissue Nervous Tissue Blood Connective Tissue dense c.t. blood vessels nerves muscle fibers with motor neurons

Tissues you’ll find in skeletal muscle

Structure of a Skeletal Muscle Connective Tissue Coverings Fascia: -separates individual muscle -holds muscle in position -dense c.t. -projects beyond muscle to form tendon

Connective Tissue Coverings

Structure of a Skeletal Muscle Connective Tissue Coverings Tendon: -may intertwine with periosteum

Connective Tissue Coverings

Structure of a Skeletal Muscle Connective Tissue Coverings Tendons : muscle to bone attachment Aponeuroses : fibrous sheets attaching to bone or to other muscle

Connective Tissue Coverings

Tendinitis & Tenosynovitis Green box on p. 286 What is it & what causes it? Where is it most commonly found? inflamed or swolen tendon due to injury or repeated stress shoulder, elbow, hip, knee movement of wrist, hand, thigh, foot

Compartmentment Syndrome Green box on p. 286 What is it? What is the treatment? pressure on a muscle enclosed in connective tissue due to a hemmorage surgery to relieve pressure
