The range of movement allowed by particular joints can be measured using _______ that are strapped to the outside of the human body at the location of the studied joint.

It allow two-dimensional movement at articulations in the wrists and ankles.

It is a related disorder due to overuse of the finger used in shooting guns, first observed among soldiers who fired rifles on the rifle range for many hours of the day.

It is a large ball and socket joint that is deep within the pelvis, it can carry heavy loads over a small range of movement.

These are joints where a protrusion from one bone fits into a recess of another.

This disorder involves inflammation of the tendon sheaths at the base of the thumb.

Within a joint, it hold the bones together.

People who has this disorder often feel numbness or tingling in their hands, usually at night.

It is adjacent to the carpal tunnel away from the thumb side, and provides a conduit for the ulnar nerve and artery.

The contact surfaces of bones in a joint are normally covered with a thin, smooth, and very slippery layer of collagen fibers.

It act as a shock absorber and also helps minimize friction forces.

Two important types of joints found in the human body.

The human skeleton consists of two principal systems of levers

This syndrome is painful and can severely restrict movement of the thumb.

It occur at the locations where bones come together, or articulate.

Joints at the ends of the fingers, knee joints, and elbow joints are known as.

It consists of two principal systems of levers, the arms and legs, which are flexibly connected to the central body structure consisting of the skull, spine, rib cage, and pelvis.

This are consciously controlled to modify the environment and acquire information.

That tunnel is formed by the u-shaped carpal bones at the base of the back of the hand and the transverse carpal ligaments forming the opposite side below the palm of the hand.

It have inelastic ligaments stretching down each side that prevent sideways movements.

It is a disorder resulting from compression of nerves and blood vessels beneath the collarbone, which can cause the arms to become numb and interfere with movement.

How many bones does human skeleton contains?

It make up most of the articulating joints of the upper and lower extremities.

This act in various ways to keep the other systems functioning.

These are examples of spherical joints similar to trailer hitches.

It is caused by swelling and irritation of the synovial membranes around the tendons in the carpal tunnel, and that swelling puts pressure on the median nerve.

It tend to be complex structures, made from many different materials besides bone.

It occurs when ligaments are torn or stretched beyond their limits.

Bones in the ______ are structure like pipes, with closed ends near the joints.

This disorder occurs when ligaments are stretched to the point that they no longer hold the lower part of the ulna bone in place, resulting in permanent disability.

This are stimulated by energy sources (light, sound, or heat) or materials (air-borne chemicals, acid on skin, salt on tongue) in the outside environment.

It found at the base of the thumb also allows two-dimensional movement.

Most ligaments and tendons are made from ______?

The forearm has two bones which connect the elbow to the carpal bones of the wrist.

Those are very well engineered and work beautifully as long as they are not subjected to stresses beyond their design limits.

This processes information acquired from the sensory systems.

It is the joint at the base of the thumb where the carpal bones articulates with the metacarpal bones within the hand.

It is normally present at the spot where the tendon attaches.

It is one of the most common of the cumulative trauma disorders.

It involves both the hand and the wrist.

Muscles are attached to the bones by ____?

This are found principally in the spine

It is smaller and not nearly as deep within the shoulder bone, so it cannot take as great a load, although it has a greater range of movement than the hip joint.
