Practical 3 Worksheet – Trunk Name_________________________________________ Date__________________ The vertebral column consists of 26 bones stacked on top of each other that run from C1 all the way down to the Coccyx. There are ______________ Cervical Vertebrae, ______________ Thoracic Vertebrae, and ______________ Lumbar Vertebrae. In short, the neck area of the vertebral column is called the __________ region, the rib cage is called the ____________ region, and the lower back is called the _____________ region. Why do you think the Lumbar region’s vertebrae are larger then the Thoracic or Cervical vertebrae? The Sacrum and the Coccyx are fused bones. What does that mean? Name all the muscles that act at the trunk and contribute to the below listed movements: Flexion-­‐ Extension-­‐ Lateral Flexion (Right)-­‐ Lateral Flexion (Left)-­‐ Trunk Rotation (Right)-­‐ Trunk Rotation (Left)-­‐ Compression-­‐ Is the External Oblique superficial or deep to the Internal Oblique? Is the Internal Oblique superficial or deep to the Transverse Abdominis? Match the direction of each muscles fiber arrangement: Rectus Abdominis Horizontal External Oblique Internal Oblique Vertical Transverse Abdominis Erector Spinae Diagonal Quadratus Lumborum What are the three divisions of the Erector Spinae and name them from most medial to most lateral? The Linea Alba and the ___________________ ________________________ give the Rectus Abdominis muscle its 6-­‐pack lobed look. (True / False) The muscles that act at the trunk can only create a flexion movement. So, it makes sense that a personal trainer focuses mainly on crunches when targeting a client’s core. Name two sports movements that would benefit from a strong “core”, which would allow an efficient transfer of energy from the legs, through the hips/core, and into the upper body. As a group, brainstorm and list 3 exercises that target the core musculature in the three different planes of motion and name the muscles that are targeted. Sagittal-­‐ Frontal-­‐ Transverse-­‐ Using the same 9 exercises fill in the below table: Exercise Movement(s) Plane of Name Motion Axis of Rotation Muscle(s) Targeted What is the difference between Lordosis and Kyphosis? Name an everyday activity that contributes to an anterior tilt of the pelvis. What are the characteristics that define and differentiate the Local Stabilization System, the Global Stabilization System, and the Movement System?
