Muscle Types & Movements

Explore the three main types of muscles in the human body: cardiac, smooth, and skeletal. Cardiac muscle is involuntary, striated, and features intercalated discs for rhythmic contractions. Smooth muscle, also involuntary and non-striated, operates in hollow organs such as the digestive tract and arteries. Skeletal muscle is voluntary and striated, allowing for movement by connecting to bones. Discover muscle origins, insertions, and actions, as well as key movements like flexion, extension, abduction, and adduction, vital for understanding body mechanics.

Presentation Transcript

  1. Muscle Types & Movements Anatomy & Physiology Mrs. Halkuff

  2. Cardiac Muscle • Involuntary • Striated • Intercalated Discs • Contract in rhythmic fashion 3 Types of Muscle

  3. Smooth Muscle • Involuntary • Nonstriated • Lines hollow organs: arteries, digestive tract, bladder, uterus, & lungs 3 Types of Muscle

  4. SkeletalMuscle • Voluntary • Striated • Connect to the bones to produce movement. • 640 muscles in the body. 3 Types of Muscle

  5. Movement is produced by the contraction of muscles. • All descriptions of position and movement assume anatomical position.

  6. Muscles have an Origin, Insertion, & Action. • Origin: Muscle attachment to an immovable bone. • Insertion: Muscle attachment to a moveable bone. • Movement is a muscle’s insertion moving toward or way from its origin. • Action: The movement that is produced from the muscle. Origin, Insertion, & Action

  7. ADJUSTING AN ANGLE BETWEEN TWO BODY PARTS • Flexion: Reduces the angle between two articulating elements. • Extension: Increases the angle between two articulating elements.

  8. ADJUSTING THE BODY IN RELATION TO THE MIDLINE OF THE BODY • Abduction: Movement away from the center/midline. • Adduction: Movement toward the midline of the body. Refers to the appendicular skeleton only.

  9. MOTIONS IN AN ARC • Rotation: Turning the body on an axis, such as shaking your head ‘no’. • Circumduction: Circular movements.

  10. ROTATION OF THE FOREARM • Pronation: Palm up to palm down. • Supination: Palm down to palm up

  11. MEDIAL & LATERAL FLEXION OF FOOT • Inversion: Movement of the foot inward, toward the median plane. • Eversion: Movement of the foot outward, away from the median plane.

  12. FLEXION OF ENTIRE FOOT • Dorsiflexion: Elevating the sole and digging the heel. • Plantar Flexion: Extending the ankle and elevating the heel. Pointing the toes.
