Saddle Joint
Circumduction and rotation ARE possible around the hip joint.
Circumduction and rotation ARE possible around the hip joint.
Thumb abduction and adduction is in the sagittal plane. However, finger abduction and adduction is in the frontal/coronal plane. Do these movements in the anatomical position and that will help you see that the thumb is not abducting or adducting in the frontal plane rather the sagittal plane.
No, the human head is not capable of circumduction, which is a circular movement around an axis. The head is primarily designed for flexion, extension, rotation, and lateral flexion movements.
The muscles that are involved in the circumduction of the shoulder joint are the pectoralis major, deltoid, supraspinatus, long head of triceps, biceps brachii, subscapularis, infraspinatus, coracobrachialis, teres major and minor and the latissimus dorsi.
Shoulder circumduction is a multiplanar motion that occurs in the sagittal, frontal, and transverse planes. It involves a combination of flexion, extension, abduction, adduction, and internal and external rotation at the shoulder joint.
Circumduction and rotation ARE possible around the hip joint.
No, a thumb tack is not an inclined plane simple machine. An inclined plane is a flat surface that is tilted, like a ramp, that allows objects to be raised or lowered with less force. A thumb tack is a fastener that uses a sharp point to pierce through materials.

A bike, a car, a plane, a helicopter, or a thumb!
This is a saddle joint which allows movement in two planes instead of one. It allows the thumb to cross the palm of the hand. This joint allows biaxial movement. This allows movement in the frontal and sagittal planes.
