Anterior view of the left shoulder and acromioclavicular joints, and proper scapular ligaments. The glenohumeral (GH) joint is a true synovial ball-and-socket style diarthroidal joint that is responsible for connecting the upper extremity to the trunk.It is one of four joints that comprise the shoulder complex.This joint is formed from the combination of the humeral head and the glenoid fossa of the scapula.ogether, the joint capsule and the ligaments of the GH joint work to provide a passive restraint to keep the humeral head in contact with the glenoid fossa.
Insects, arachnids, centipedes and crustaceans are all arthropods.   An arthropod is an invertabrate animal that has an exoskeleton, a segmented body, and jointed appendages.    An ANTHROPOD is a bipedal humanoid (ie Homo Sapien, Homo Neanderthalus, Homo Habilus, Australopithicene Afarensis, and other hominids).irds, reptiles, fish, and even sometimes other arthropods eat each other.
Terrestrial arthropods use a system called the Malpighian Tubule System to remove wastes from their bodies. It is made up of branching tubules which connect to the blood stream. Keep in mind that arthropods do not have blood but a blood equivalent called hemolymph which is a mix of blood, intercellular fluid, and lymph.orseshoe crabs (Limulidae) are another example of arthropods. They use a mix of methods to excrete wastes from both terrestrial and aquatic arthropods. They secrete wastes through the gills while at the same time are able to excrete feces through and anus and excrete urine as well by using kidneys.
