Class Outline: Anterior Anatomy 5 minutes Breath of Arrival and - PowerPoint PPT Presentation

Class Outline: Anterior Anatomy  5 minutes Breath of Arrival and Attendance  5 minutes Howdy Partner  35 minutes Anterior Anatomy using Power Point Presentation ◦ 5 minutes Overview of skeletal segments ◦ 5 minutes Quick drawing of the superficial muscles (Salvo page 420) Review each skeletal segment adding muscle names, origins, insertions ◦ 25 minutes  10 minutes Quadriceps femoris

Classroom Rules Punctuality- everybody's time is precious: ◦ Be ready to learn by 9:00, we'll have you out of here by 1:30 ◦ Tardiness: arriving late, late return after breaks, leaving early The following are not allowed: ◦ Bare feet ◦ Side talking ◦ Lying down ◦ Inappropriate clothing ◦ Food or drink except water ◦ Phones in classrooms, clinic or bathrooms You will receive one verbal warning, then you'll have to leave the room.

Anterior Anatomy Names, locations, and shapes of muscles

Anterior Skeletal Segments Giving names to the bones on the back of the body.

Anterior Anatomy As we explore the skeletal segments, label them with the images supplied.

The Big Picture

Head Bones: cranium, face bones, mandible (lower jaw)

Neck Bones: cervical spine

Trunk Bones: thoracic spine, lumbar spine, and rib cage

Shoulder Girdle Bones: collar bone (clavicle) and shoulder blade (scapula)

Arm (upper extremity) Bones: arm bone (humerus), forearm bones (radius and ulna), and hand bones

Pelvic Girdle Bones: pelvic bones and tail bone (sacrum and coccyx)

Thigh Bones: thigh bone (femur) and knee cap (patella)

Leg Bones: lower leg bones (tibia and fibula)

Foot Bones: foot bones

Anterior Muscles Giving names, shapes and locations to muscles

Let’s draw the superficial muscles!

Head These muscles will be covered in Class 11a: Muscles of the Head / Neck

Neck Details in a future class, but for now this is SCM

Trunk Thorax and Lumbar Vertebrae

Trunk Muscle: pectoralis major (pecs) Origin: medial ribcage and clavicle Insertion: proximal arm (humerus)

Trunk Muscle: pectoralis major (pecs) Origin: medial ribcage and clavicle Insertion: proximal arm (humerus)

Trunk Muscle: rectus abdominis (abs) Origin: medial pelvis Insertion: medial ribcage

Trunk Muscle: rectus abdominis (abs) Origin: medial pelvis Insertion: medial ribcage

Arm

Arm Muscle: deltoid (anterior deltoid) Origin: shoulder girdle Insertion: arm (humerus)

Arm Muscle: deltoid (anterior and middle deltoid) Origin: shoulder girdle Insertion: arm (humerus)

Arm Muscle: biceps brachii (biceps) Origin: shoulder girdle Insertion: forearm (radius)

Arm Muscle: biceps brachii (biceps) Origin: shoulder girdle Insertion: forearm (radius)

Forearm Muscle: forearm flexors Origin: distal arm (humerus) Insertion: fingers

Forearm Muscle: forearm flexors Origin: distal arm (humerus) Insertion: fingers

Pelvis Gluteal muscles

Pelvis Muscle: TFL (tensor fascia latae) Origin: pelvis Insertion: fascia ( iliotibial band )

Pelvis Muscle: TFL (tensor fascia latae) Origin: pelvis Insertion: fascia ( iliotibial band )

Thigh Bones: thigh bone (femur) and knee cap (patella)

Thigh Muscle: sartorius Origin: pelvis Insertion: proximal leg (tibia)

Thigh Muscle: sartorius Origin: pelvis Insertion: proximal leg (tibia)

Thigh Muscle: quadriceps femoris (quads) Origin: pelvis and thigh Insertion: upper leg (proximal tibia)

Thigh Muscle: adductor group Origin: pelvis Insertion: thigh (femur)

Leg

Leg Muscle: tibialis anterior Origin: anterior leg (tibia) Insertion: medial foot

Leg Muscle: peroneus longus Origin: lateral leg (fibula) Insertion: medial foot

Positioning of Leg Muscles tibialis anterior soleus

Review of Muscle Names

Pectoralis major Rectus abdominis Deltoid Biceps brachii Forearm flexors TFL Sartorius Quadriceps Tibialis anterior Peroneus longus

Trapezius Rhomboids Levator scapula Erector spinae Lats Deltoid Triceps Forearm extensors Gluteus maximus Gluteus medius Biceps femoris Semitendinosus Semimembranosus Gastrocnemius Soleus

OIA’s (origin, insertion, and action) Belly The wide central portion of a skeletal muscle. Tendon Cord-like structure anchoring the end of a muscle to a bone. Origin Tendinous muscle attachment on the less movable bone. Insertion Tendinous muscle attachment on the more movable bone. Action The movement caused by the contraction of a muscle.

Quadriceps Femoris

Rectus femoris Origin: anterior inferior iliac spine (ASIS) Insertion: patella tibial tuberosity Action: flex the hip (femur) extend the knee (tibia)

Vastus medialis Origin: medial lip of linea aspera Insertion: patella tibial tuberosity Action: extend the knee (tibia)

Vastus lateralis Origin: lateral lip of linea aspera gluteal tuberosity Insertion: patella tibial tuberosity Action: extend the knee (tibia)

Vastus intermedius Origin: anterior and lateral shaft of the femur Insertion: patella tibial tuberosity Action: extend the knee (tibia)
