Transcript of Jumping Jacks
Jumping Jacks! Movements Involved Flexion and Extension Abduction and Adduction Dorsiflexion and Plantar Flexion Muscles Involved Deltoids Medial and anterior when arms are above head. Trapezius Upper trapezius when arms are raised above head Serratus Anterior Arms swing above head and brought to sides. Abductors Thigh moves away from body and hips are abducted. Gluteus maximus, medius, mimimus, tensor fascia lata Adductors Pectineus, gracilis, adductor magnus, adductor brevis, adductor longus. Thigh is moved towards mid-line of body, hips are adducted. Calves Gastronemius and soleus. Hop off of floor and toes pointed downward. Abs Rectus abdominis and obliques contract to stabilize the spine and create force. Bones Used Lower Legs and Feet Tibia, fibula, tarsals, metatarsals, phalanges. Tibia and fibula give support and attach to soleus, hamgstrings, and quadriceps. Upper Legs and Hips Femur and hip bones support legs and gastrocnemius, quadriceps, adductors, abductors and hamstrings. Hip bones attach to abdominal muscles and stabilize femur. Spine and Ribs Vertebrae keep body upright during movement and is attached to back muscles. Ribs allow for deep breathing with intercostal muscles and attach to abdominal muscles. Arms and Shoulders Clavicle, scapula, and humerus make up shoulder joint and attach to deltoids, trapezius, and pectoralis major. Joints Used Ankles Hinge Joint Knees Hinge and Pivot Joint Hips Ball and Socket Joint Shoulder Ball and Socket Joint Elbow Hinge Joint Nervous System Nerve impulses start in Central Nervous System.Full transcript
Nerve signals are sent throughout the body in order to initiate movement in the skeletal muscles.
Nerve signals are involved throughout the movement because it is a repeated motion. How are all three systems connected? Nervous System Sends messages to skeletal muscles to create movement. Muscular System Skeletal muscles move the body by moving the bones that are connected to them. Skeletal System Gives support for the muscular system.
