Discuss MT r/t the Muscular System Discuss the (4) characteristics of muscles Discuss the (3) main types of muscles Differentiate tendon and fascia Draw and label the (14) main muscles Objectives: SWBAT

Take notes in these sections using the info in the PowerPoint Divide your paper into 4 equal sections (you can do this easily by folding it or using a ruler if you want to separate the sections by drawing lines. Label your paper like this: Take notes in these sections using the info in the PowerPoint

Divide the back of the same paper and label like this:

BELLWORK- add these to the top left of your foldable -algia (pain) Muscul- (muscle) -fascia (fibrous) Fibr- (fibers) My/o- (muscle) (myalgia = muscle pain) Ten-/Tend-/Tendin- (tendon) ROM (range of motion)

What is the Muscular System? System composed of over 600 muscles (bundles of muscle fibers held together by connective tissue (think of a twizzler)) Muscles contain the following characteristics Excitability (can respond to a stimulus) Contractibility (become short & thick to cause movement) Extensibility (can be stretched) Elasticity (returns to normal after contracted or stretched) 3 types of muscle Cardiac (walls of heart) Visceral (smooth) (in internal organs (GI system, eyes)) Skeletal (attached to bone to cause movement) What is the Muscular System? Involuntary Voluntary

Skeletal Muscles have (4) functions Attach to bones to provide voluntary movement (Can you move your body as you want to, when you want to?? Thank you muscles!!) Produce heat and energy for the body ( Do you have more energy before or after your work out? Are you warmer before or after you play a game of basketball?) Maintain posture by holding the body upright (Can posture be controlled?) Protect internal organs (Can you touch your intestines? How about your lungs or heart?) Skeletal Muscles have (4) functions

How do muscles attach to bones? Tendons (strong, tough, connective tissue cords (think of a bungee cord!)) Fascia (tough, sheet-like membrane that covers and protects (think of a trampoline (elastic and movable, yet strong))

There are more than 600 muscles in the human body

Muscles can get their name by their location (like the SCM), because of their size (gluteus maximus), by their shape (trapezius) or by the number of heads (biceps (bi-=two; -cep= head)) n This muscle attaches to the sternum (sterno-), the clavicle (cleido-) and the mastoid process

Draw a person (can be a stick person) to add and label muscles

Main Muscles Add muscle name and description to your drawing p. 167 Sternocleidomastoid (SCM) Pectoralis Major (chest) Deltoid (upper/side of arm)(injection site) Biceps Brachii (muscle with 2 heads at the front of upper arm) Triceps Brachii (muscle with 3 heads at the back of upper arm) Intercostals (inter=between; costae= ribs) Rectus Abdominus (Abs)(Abd; rectus= straight) Trapezius (Upper Back/Neck)(“Massage my trapezius please”  ) Lattisimus Dorsi (Dorsal = back) Gluteus Maximus (Maximus= large muscle) (injection site) Gastrocnemius (Calf) Quadriceps Femoris (muscle with 4 heads on top of femur) (injection site) Sartorius (crosses over thigh like a seat belt) Tibialis Anterior (front of tibia) Main Muscles Add muscle name and description to your drawing p. 167

Muscles are partially contracted at all times so that they are ready to act when they need to, this is called muscle tone. (Can muscle tone be lost? Yes, illnesses such as paralysis can cause decreased muscle tone. Decreased muscle use leads to atrophy (decrease in size and strength) of muscles. Lack of use can also lead to contractures, which is severe tightening of a flexor muscle resulting in bending of a joint (foot drop).) Muscles have various movements Adduction (“adding” toward midline) Abduction (“taking” away from midline) Flexion (bending) Extension (straightening) Rotation (turning around an axis (moving head side to side)) Circumduction (moving in a circle at a joint) How do muscles work?
