The elbow is a “hinge” joint formed by the distal end of the humerus and the proximal ends of the radius and ulna bones. The elbow moves into flexion and extension. The trochlea and capitulum of the humerus articulate with the trochlear notch of the ulna and the radial head, respectively.
The specific articulations of the elbo…
The bones involved in ankle articulation include the tibia, fibula and talus. The tibia and fibula are the long bones of the lower leg; the fibula, a relatively thinner bone, is lateral to the tibia. These two bones are bound together by the ligaments and the interosseous membrane.Read More
The spinal cord begins as an extension of the brain. It is surrounded by the bony vertebral column, which acts as a protective mechanism. Any information (sensory or motor) that the brain needs to relay to the body travels via the spinal cord. Fortunately, the spinal cord is protected by vertebrae, so spinal-cord injuries are not common, and most …Read More
The past three Fine Anatomy articles have examined movements of the shoulder and the shoulder girdle. Because the shoulder is an immensely complex structure, personal trainers must invest a significant amount of time and effort learning its “functional pathologies” and understanding basic anatomy in order to create sound exercise program design.Read More
TThe multiarticular complex of the shoulder gives rise to the dynamic movement potential of the arm at the glenohumeral joint. If it were not for the physiological necessity of the scapulo-thoracic “joint” (discussed in the previous Fine Anatomy column, “The Shoulder Girdle,” IDEA Personal Trainer, October 2003, p.36) and its role during abduction or flexion of the upper limb to elevate, rotate, tilt and swivel, the elementary movements of the arm would be greatly limited.Read More
The closer we look at movement or the potential movement of the human body, the more dynamic, intricate and specific it becomes. When studying the appendicular skeleton, personal trainers will benefit from understanding ideal range of motion (ROM), joint articulation and the influence of the axial skeleton on limb action. The Scapula and Stance The…Read More
Because the ground constantly has variables, human feet need to adapt to their interface with it immediately on contact. In normal function and anatomical position, the ankle joint has extension (dorsiflexion) and flexion (plantar flexion). All other movements in the ankle region are created by the foot’s dynamic joint structure. The ankle is composed of…Read More
This is the eighth in a series of articles that address how muscles work synergistically to create efficient movement at each joint. The previous article examined the muscles that support the thoracic spine; this discussion covers the posterior muscles of the cervical spine. The cervical spine’s muscle functions are more intricate and delicate than those…Read More
