1. The FAITH Prayer We praise and thank you dear GOD For the blessings you have showered upon us. Empower us that we may have: The INTELLIGENCE to be competent and perform in the best way we can; The WILL for total commitment to truth, justice, freedom, peace and unity Among people and the environment; And the HEART to be compassionate and sensitive to the needs of others especially the poor. This we ask in the name of Mary, our Mother and Jesus our Lord. AMEN

3. BPESPE2 - Anatomy and Physiology of Human Movement Question Number 1:

4. ▪ Produces movement ▪ Generates Heat ▪ Maintains posture ▪ Stabilizes joints BPESPE2 - Anatomy and Physiology of Human Movement Function of the Muscular System:

5. BPESPE2 - Anatomy and Physiology of Human Movement Properties of Muscle Excitability: capacity of muscle to respond to a stimulus Contractility: ability of a muscle to shorten and generate pulling force Extensibility: Muscle can be stretched without being damaged Elasticity: ability of muscle to recoil to original resting length and shape after being stretched

6. BPESPE2 - Anatomy and Physiology of Human Movement Properties of Muscle

7. BPESPE2 - Anatomy and Physiology of Human Movement Three Types of Muscles in our Body:

8. BPESPE2 - Anatomy and Physiology of Human Movement Three Types of Muscles in our Body:

9. BPESPE2 - Anatomy and Physiology of Human Movement Characteristics of Skeletal Muscle ● Most are attached to bones by tendons ● Cells are multinucleated ● Striated –have visible banding patterns ● Voluntary- subject to conscious control ● Cells are surrounded and bundled by connective tissue

10. BPESPE2 - Anatomy and Physiology of Human Movement Characteristics of Cardiac Muscle ● Has STRIATIONS ● Usually has a single nucleus ● Joined to another muscle cell at an intercalated disc ● Involuntary- no conscious control ● Found only in the heart

11. BPESPE2 - Anatomy and Physiology of Human Movement Characteristics of Smooth Muscle ● Has NO STRIATIONS ● Spindle-shaped cells ● Single nucleus ● Involuntary- no conscious control ● Found mainly in the walls of hollow organs

12. BPESPE2 - Anatomy and Physiology of Human Movement Naming of Skeletal Muscles ● Directions of Muscle fibers Example: rectus (straight) ● Relative size of the muscle Example: maximus (largest) ● Location of the muscle Example: temporalis (muscle attached to temporal bone) ● Number of origins Example: triceps (three heads) Origin: attachment to bone that does NOT move Insertion: attachment to bone that MOVES

13. BPESPE2 - Anatomy and Physiology of Human Movement Naming of Skeletal Muscles ● Location of the muscle’s origin and insertion Example: sterno (on the sternum) ● Shape of the muscle Example: deltoid (triangular); trapezius (trapezoid shaped ● Action of the muscle Example: flexors (flexes a bone); extensors (extends a bone)

14. BPESPE2 - Anatomy and Physiology of Human Movement Muscles and their Function: ● Biceps – flexes lower arm ● Deltoid – abducts arm; injection site ● Sternocleidomastoid – turns head ● Gastrocnemius – flexes sole of feet ● Latissiumus dorsi – extends & adducts upper arm ● Pectoralis major– adducts and flexes upper arm

15. BPESPE2 - Anatomy and Physiology of Human Movement Muscles and their Function: ● Trapezius – extends head, moves shoulder ● Triceps – extends lower arm ● Gluteus maximus – extends thigh; injection site ● Sartorius – abducts thigh, flexes leg ● Rectus abdominis– compresses the abdomen ● Rectus femoris– flexes thigh & extends lower leg ● Tibialis anterior– flexes & inverts foot

BPESPE2 - Anatomy and Physiology of Human Movement Asynchronous Activity: Name of the Muscle Origin Insertion Action Innervation (Nerve Supply) Orbicularis oris Maxilla and mandible Skin and muscle around the mouth “kissing muscle” closes and protrudes lips Cranial nerve 7 Frontalis Occipitalis Orbicularis oculi Buccinator Platysma Hyoglossus

25. BPESPE2 - Anatomy and Physiology of Human Movement Asynchronous Activity: Name of the Muscle Origin Insertion Action Innervation (Nerve Supply) Temporalis Masseter Sternocleidomastoid Trapezius External intercostals Internal intercostals External abdominal oblique

26. BPESPE2 - Anatomy and Physiology of Human Movement Asynchronous Activity: Name of the Muscle Origin Insertion Action Innervation (Nerve Supply) Rectus abdominis Erector spinae External urethral sphincter Compressor urethrae External anal sphincter Pectoralis minor Pectoralis major

27. BPESPE2 - Anatomy and Physiology of Human Movement Asynchronous Activity: Name of the Muscle Origin Insertion Action Innervation (Nerve Supply) Latissimus dorsi Deltoid Brachialis Biceps brachii Brachioradialis Pronator quadratus Pronator teres

28. BPESPE2 - Anatomy and Physiology of Human Movement Asynchronous Activity: Name of the Muscle Origin Insertion Action Innervation (Nerve Supply) Supinator Flexor carpiulnaris Extensor carpiulnaris Iliacus Tensor fasciae latae Gluteus maximus Gluteus medius

29. BPESPE2 - Anatomy and Physiology of Human Movement Asynchronous Activity: Name of the Muscle Origin Insertion Action Innervation (Nerve Supply) Quadratus femoris Piriformis Rectus femoris Semitendinosus Gastrocnemius Soleus
