Presentation on theme: "Read the HIV article silently."— Presentation transcript:
1Read the HIV article silently. Warm-upRead the HIV article silently.Partner A – beginning to how can a person reduce their risk of getting HIV?Partner B – who is at risk to the end
2What are 10 muscles located superior to the pelvic cavity? LEQWhat are 10 muscles located superior to the pelvic cavity?
3How muscles contract Muscles can only pull, not push! To pull, muscles contract.When muscles contract they shorten.Muscles shorten because the muscles fibers slide past each other.The sliding is like a trombone
4Muscle Terms Hypertrophy ~ increase in size of a muscle Due to overuse Purposely done by athletesAtrophy ~ decrease in size of a muscleWasting awayLack of exercise : broken legNormal aging processDelayed with exercise
5Muscle TermsMost movement is performed by groups of muscles working together; however, a single muscle is generally responsible for MOST of the movement.Prime mover ~ Chief muscle (responsible for movement)Synergist ~ helper musclesAntagonists ~ oppose the action of another muscleMuscle pairs
6Form the abdominal wall Move the vertebral column Muscles of the TrunkInvolved in breathingForm the abdominal wallMove the vertebral columnForm the pelvic region
7Muscles for Breathing Intercostal Muscles ~ located between the ribs Origin and insertion on the ribsResponsible for raising and lowering the rib cage during breathing
8Muscles for BreathingDiaphragm ~ dome- shaped muscle that separates the thoracic cavity from the abdominal cavityChief muscle of inhalation
9Muscles of the Abdominal Wall Consists of 4 musclesMuscles are layered at different depthsFibers of these muscles run in different directionsContain, support and protect abdominal organsContraction causes flexion and rotation of vertebral column, urination, defecation, and childbirth.
10Abdominal Muscles Rectus abdominis ~ fibers run up and down Contraction flexes the vertebraeIncreases intra-abdominal pressure
11Abdominal Wall Muscles External oblique ~ lateral walls of the abdomenFibers run obliquely (slanted)Aids rectus abdominus (trunk rotation/lateral flexion)
12Abdominal Wall Muscles Internal oblique ~ add strength to the external oblique (crisscross with them)
13Abdominal Wall Muscles Transverse abdominis ~ fibers run horizontallyInnermost layer of the abdominal musclesResponsible for compression
16Muscles of the Vertebral Column Attach to the vertebraeMove the vertebral column in numerous directionsNumerous muscles….will not discuss in detail.
17Muscles of the Shoulder Trapezius ~ origin in bases of the occipital bone and inserts on the scapula and clavicleHyperextends headContraction allows for shrugging and rotating movementRight and left trapezius form the shape of a trapezoid
19Muscles of the Shoulder Pectoralis Major ~ forms the anterior chest wallConnects the humerus with the clavicle and sternumContraction moves the arm across the chestAdducts the arm
20Muscles of the Shoulder Deltoid ~ forms the rounded portion of your shoulder (shoulder pad)Contraction abducts the arm
21Muscles of the Shoulder Latissimus dorsi ~ Broad muscle located in the middle and lower back region.Origin vertebrae, insertion humerusAdducts shoulders and extends arm back.“Swimmers muscle”
22Muscles that Move the Forearm Triceps brachii ~ located on the posterior surface of the humerus.Prime mover of extension of the forearmSupports weight for push-upsBoxer muscle ~ packs the greatest punch
23What are 10 muscles located superior to the pelvic cavity? LEQWhat are 10 muscles located superior to the pelvic cavity?
24Read the Herpes article A - Beginning to symptoms Warm-upRead the Herpes articleA - Beginning to symptomsB - Contagious to end
25What is a prime mover? Synergist? Antagonist? Hypertrophy? Atrophy? Let’s review!What is a prime mover?Synergist?Antagonist?Hypertrophy?Atrophy?Flexion?Extension?Origin?Insertion?Contraction?
26Muscles that Move the Forearm Biceps brachii ~ located along the anterior surface of the humerusFlexes the forearm“Make a muscle”
27Muscles that Move the Forearm Brachioradialis ~ synergist of biceps brachiiOrigin on humerus, Inserts on radiusFlexes forearm at elbow
28Muscles that Move the Wrist, Hand, and Fingers More than 20 musclesSmall which makes for delicate movementGenerally located along the forearmThe tendons of these muscles pass through the wrist into the hand and fingers.
29Muscles that Move the Wrist, Hand, and Fingers Flexor digitorum ~ flexes fingersAnterior muscle
30Muscles that Move the Wrist, Hand, and Fingers Extensor digitorum ~ extends fingersPosterior muscle
32Story time!Create a story using the movements from 15 different muscles.For example, Jack makes a fist because he is so mad!Underline makes a fist.You may use all facial muscles and muscles superior to the pelvic cavity.You may not say abduct, adduct…Another reader will identify the muscle responsible for that action.
33Warm-upComplete the muscle action chart using your brain – refer to notes if necessary.
34Collect Health Fair reflections Collect movie packet CC Health Day AgendaCollect Health Fair reflectionsCollect movie packetCC Health DayRemind appTest on muscles on Friday
35What are 10 muscles located superior to the pelvic cavity? LEQWhat are 10 muscles located superior to the pelvic cavity?
36What are 10 muscles located inferior to the pelvic cavity? LeqWhat are 10 muscles located inferior to the pelvic cavity?
37Muscles of the Pelvic Floor Assist in expelling contents from the urinary bladder and rectumWill not be discussed in detail
38Muscles that Move the Thigh, Leg, and Foot Some of the largest and strongest muscles of the bodyMove the lower extremitiesHelp maintain posture
39Gluteal Muscles Located on the posterior surface Gluteus maximus ~ forms the area of the buttocksLargest muscle of the bodyRotates the thigh laterally and extends the thigh at the hip (walking, stair climbing)
40Gluteus medius ~ abduct and rotate the thigh medially at the hip Gluteal MusclesGluteus medius ~ abduct and rotate the thigh medially at the hip
41Muscles that Move the Leg Located on the thighExtensor muscles lie along the anterior and lateral surfaces.Flexors lie along the posterior and medial surfaces
42Muscles that Move the Leg Quadriceps Femoris ~ located on the anterior thighMost powerful muscle in the bodyContain four different partsVastus lateralisVastus intermediusVastus medialisRectus femorisAll four parts cause extension of the leg at the knee
59Classifying muscles All muscles superior/inferior to pelvic cavity All muscles on the faceAll muscles on the armAll muscles in the trunkAll muscles in legsAnterior muscles in anatomical orderPosterior muscles in anatomical order
60Little Red Riding HoodRead the Little Red Riding Hood story with your partner. Tell me which muscle is responsible for which movement. Use your notes to help you find the correct answers.
