問題一覧

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.

sensory systems

This processes information acquired from the sensory systems.

central information processor

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

effector systems

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

support systems

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.

human skeleton

The human skeleton consists of two principal systems of levers

arms and legs

How many bones does human skeleton contains?

200 bones

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

extremities

Muscles are attached to the bones by ____?

tendons

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

bone depression or protrusion

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

joints

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

joints

Within a joint, it hold the bones together.

ligaments and muscles

Most ligaments and tendons are made from ______?

inelastic collagen fibers

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

cartilage

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

cartilage

Two important types of joints found in the human body.

synovial joints, cartilaginous joints

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

synovial joints

This are found principally in the spine

cartilaginous joints

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

hinge joints

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

hinge joints

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

gliding joints

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

saddle joints

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

saddle joints

These are examples of spherical joints similar to trailer hitches.

hip and shoulder joints

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.

hip joints

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.

shoulder joints

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

pivot joints

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

radius and ulna

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.

goniometers

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

synovial joints

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

sprains

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.

ulnar deviation

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

dequervain's disease

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

dequervain's disease

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.

trigger finger

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.

thoracic outlet syndrome

It involves both the hand and the wrist.

carpal tunnel syndrome

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

carpal tunnel syndrome

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

carpal tunnel syndrome

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.

carpal tunnel syndrome

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

guyon canal

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.

carpal tunnel
