the center of the body, dividing It into equal right and
left halves

Answer 1

median plane

Question 2

is any plane parallel to the median
plane that divides the body into unequal right and
left portions.

Answer 2

sagittal plane

Question 3

a vertical plane situated at a right angle to the median plane. This plane divides the body into anterior (front) and posterior (back) portions.

Answer 3

coronal (frontal) plane

Question 4

Lies at right angles to both the
median and the coronal planes. It
divides the body into upper and lower parts.

Answer 4

Horizontal plane

axis of a given structure and divides that structure in a cross-sectional orientation. T

Answer 5

Transverse plane

Question 6

is the movement in which a joint angle is decreased (closed) during motion occurring in a sagittal plane.

Answer 6

Flexion

Question 7

the joint angle is increased (opened; straightened) in a
sagittal plane

Answer 7

Extension

Question 8

is movement away from the midline of the body in the coronal plane.

Answer 8

Abduction

Question 9

is movement toward the midline of the body in the coronal plane

Answer 9

Adduction

Question 10

is the term applied to the movement of a part of the body around its long axis, with little
to no movement through space

Answer 10

Rotation

Question 11

is the movement that results in the anterior surface of the part facing medially

Answer 11

Question 12

is the movement that results in
the anterior surface of the part facing laterally

Answer 12

lateral (external) rotation

Question 13

Question 15

ls the term used to describe moving a body part forward.

is to move a part backward.

Answer 15

Protraction

Retraction

Question 16

A thick layer of fibrous tissue called the ___covers all bone surfaces, other than the articulating
surfaces.

Answer 16

Periosteum

Question 17

Bundles of collagen fibers known
as ___extend from the periosteum into the underlying bone.

Answer 17

Sharpey’s fibers

Question 18

Bone exists in two forms: compact and cancellous. Compact bone appears as a solid mass; cancellous bone consists of a branching network of

Answer 18

trabeculae

Question 19

Flat bones are found in the vault of the skull. They are composed of thin inner and outer layers of compact bone, the ___, separated by a layer of cancellous bone, the ___.

Answer 19

compact bone= tables

cancellous bone = diploe

Question 20

is one formed within a tendon where the tendon passes over a joint.

A rounded bone embedded within a tendon or muscle, acting as a pulley to reduce stress, prevent tendon wear, and increase mechanical leverage at joint surfaces

Answer 20

Sesamoid Bones

Question 21

Bone develops directly from a connective tissue membrane

Answer 21

Membranous formation

Question 22

Bone development type: a cartilaginous model is first laid down and is later replaced by bone.

Answer 22

Endochondral formation,

Question 23

A fibrous membrane called the ___ covers the cartilage except on the exposed surfaces in Joints.

Answer 23

perichondrium (the cartilage membrane)

Question 24

Eplphyseal plates are composed of

Answer 24

Hyallne cartilage

Question 25

Joint Classification and differentiate them

Answer 25

Fibrous Joints - fibrous tissue fills the joint space - very little movement Cartilage joints - the space between the artlculatlng bony surfaces ls filled with a cartilaginous pad - 2 types: Synchondrosis & Symphysis Synovial Joints: - covered by a thin layer of hyaline cartilage and are separated by a fiuid-filled joint cavity

Question 26

is a closed fibrous sac lined internally with synovial membrane. small fluid-filled sac that acts like a cushion. its between bones and soft tissues (like muscles or tendons) to reduce friction and help parts move smoothly when a joint bends or moves.

Answer 26

Bursa

Question 27

A ___ is an injury caused by abnormal or excessive force at a Joint, but without dislocation of the Joint or fracture of a bone.

Answer 27

ligament sprain

Question 28

is a tubular bursa that surrounds a tendon

Answer 28

Synovial sheath

Question 29

The tendon invaginates the bursa from one side so that the tendon becomes suspended within the bursa by a ___ In certain situations, when the range of movement Is extensive, the mesotendon disappears or remains In the form of narrow threads, the ___

Answer 29

Mesotendon Vincula

Question 30

A skeletal muscle has two or more attachments. The more proximal, less mobile attachment ls referred to as the ___. The more distal. more mobile attachment ls the ____.

Answer 30

Origin Insertion
