Objective Recognize the functions, classification, and muscle groups in relation to Preventive Medicine.

Overview Functions of Muscles Muscle Classification Muscle Groups

Functions of Muscles Responsible for body movement Stabilizing joints Posture Heat production

Muscle Classification

Skeletal Muscle Attached to skeleton Voluntary or striated muscle Tendons and body Contract rapidly and vigorously Tires easily

Smooth Muscle Have no striations/involuntary muscle Lines internal organs and blood vessels No control Found in: digestive tract urinary bladder bronchi of the lungs

Cardiac (Heart) Muscle Found in only one place in the body Hybrid muscle Actions involuntary like smooth muscle

Muscle Components/Movement Muscle Components Origin - stationary attachment of muscle to skeleton Insertion - the point where the action of the muscle is applied, resulting in motion

Muscle Groups Major muscle groups Thoracic muscle Diaphragm Rectus abdominus

Muscle Groups - Anterior Sternocleidomastoid (neck) Pectoralis Major (arms) Muscles of the Abdominal Girdle Rectus Abdominis, External and Internal Obliques, Transversus Abdominis

Muscle Groups – Posterior Trapezius Brachi Latissimus Dorsi Erector Spinae Deltoid

Muscle Groups - Upper Limb Biceps Brachii Triceps Brachii

Muscle Groups - Lower Limb Gluteus Maximus Gluteus Medius Quadriceps Group (Anterior) Hamstring Group (Posterior)

Muscle Groups - Muscles of the Ankle and Foot Tibialis Anterior Peroneus Muscles Gastrocnemius

Objective Recognize the functions, classification, and muscle groups in relation to Public Health.
