Anatomy of Exercise - Upper Body Flashcards
What are the 2 sections that the skeleton is divided into?
Axial skeleton and Appendicular skeleton
the skeleton center, and it incudes the cranium, vertebral column, ribs, and sternum
Axial skeleton
Part of the skeleton that is composed of the arms and legs
Appendicular skeleton
Also known as the spine, provides stability throughout the trunk and neck. It protects the spinal cord and existing spinal nerves
Vertebral column
How many vertebrae does the vertebral column consist of?
24
7 cervical
12 thorical
5 lumbar
What are the names of the natural curves of the spine?
Lordosis & Kyphosis
a rounding of the upper spine that exceeds 45 degrees, which causes hunchback
Kyphosis
an abnormal curvature in the spine that occurs in the frontal plane
Scoliosis
the deepest back muscle and originates from the iliac crest and inserts on the transverse process of lumbar one through five and the lower part of the twelfth rib.
Quadratus Lumborum (QL)
The abdominal complex is comprised of which muscles?
Transversus Abdominis Rectus Abdominis, External Oblique, and Internal oblique
the deepest of the 6 abdominal muscles. It extends between the ribs and the pelvis, wrapping around the trunk from front to back. The fibers of this muscle run horizontally, similar to a back support belt.
Transversus abdominis
a muscle found on the lateral side of the abdomen. It is broad and thin. it forms one of the layers of the lateral abdominal wall along with external oblique on the outer side and transverse abdominis on the inner side. Its fibers are obliquely oriented hence the name.
Internal oblique
the largest and the most superficial of the lateral abdominal muscles. It lies beneath the thoracic and abdominal skin, covering the internal abdominal oblique and anterior halves of the ribs and intercostal muscles. Its muscular part contributes to the lateral part of the abdominal wall
External oblique
slung between the ribs and the pubic bone at the front of the pelvis. When contracting, this muscle has the characteristic bumps or bulges that are commonly called ‘the six pack’.
Rectus abdominis
What are exercises for the lower back?
- Back extension on stability ball
- Back extension machine
- Superman
- All fours limb extension
Cat & Cow stretch
Back flexibility
Child’s pose stretch
Back flexibility
________________ is another name for the shoulder joint
Glenohumeral joint
a diarthrodial joint defined by the lateral clavicle articulating with the acromion process as it projects anteriorly off the scapula.
Acromioclavicular joint
The joint is located in the spot where the clavicle (collarbone) meets the sternum (breastbone) at the base of the neck.
Sternoclavicular joint
formed by the convex surface of the posterior thoracic cage and the concave surface of the anterior scapula.
Scapulothoracic articulation
