T/F: Present-day joint classification is based on joint structure

True

The movement illustrated in the figure shown is: picture shows person lifting and lowering straight arm up from the side.

abduction

The joint depicted by the arrow is functionally classified as

amphiarthrosis

Clenching your fingers to make a fist implies which type of movement at the metacarpophalangeal joints?

angular

Dorsiflexion is associated with which of the following joints? - Atlanto-axial joint - Ankle joint - elbow joint - wrist joint - knee joint

ankle joint

Joints are structurally classified into three principle types based upon which of the following criteria? - degree of joint stability - arrangement and type of tissue between articulating bones - degree of joint movement - type of movement allowed - shape of articulating surfaces

arrangement and type of tissue between articulating bones

the scientific study of joints is called

arthrology

The hip (coxal) joint is a __________ synovial joint

ball-and-socket

_______ and flexion are opposite angular movements

extension

Identify the bone that articulates proximally with the bone indicated by the arrow: pointing at the tibia

femur

Which of the following movements are possible at a hinge joint? - pronation-supination - inversion-eversion - flexion-extension - medial and lateral rotation - protraction-retraction

flexion-extension

What causes knuckles and other joints to "crack"?

formation of gas bubbles

The simple movement that occurs when flat bone surfaces move from side-to-side and back-and-forth are

gliding movements

Which of the following is NOT a purpose of joints in the human body? - increases friction between moving parts - points of contact for multiple bones - permit varying degrees of movement - also called an articulation

increases friction between moving parts

Which motions at which joint is described in this photograph. Picture shows person rotating arm inward and outward from the stomach with elbow bent at 90 degrees

medial and lateral rotation

Identify the bones indicated by the arrows: pointing at middle portion of foot

metatarsals

Identify bone indicated by arrow number 3: pointing at knee

patella

Picture of skeletal left arm. Label the following clavicle scapula humerus radius ulna carpals metacarpals phalanges

picture

The four major categories of movements that occur at synovial joints include gliding, angular movements, special movements, and ___________

rotations

The joint depicted by the arrows is functionally classified as:

synarthrosis

Identify the group of bones that articulate PROXIMALLY with the bones indicated by arrows numbered 3: arrow pointing at metatarsals

tarsals

Identify the bone that articulates medially with the bone indicated by the arrow: pointing at the fibula

tibia

The movement of opposition occurs at which of the following labelled joints?
