Sect 1 Learning Activity 1: Definitions

Question 1

Abaxial

Answer 1

Away from the center of the body or limb

Question 2

Amphiarthrodial Joint

Answer 2

A fibrocartilagenous junction that allows limited motion between articulating bones.

Question 3

Ascending movement

Answer 3

Upward motion of one or more body parts.

Question 4

Axial skeleton

Answer 4

Consists of the horse’s head, vertebral column, and sacrum

Question 5

Biomechanical lameness

Answer 5

Altered movement made in an attempt to accommodate restricted or exaggerated action of one or more parts of the horse’s anatomy (usually the limbs).

Question 6

Circumduction

Answer 6

The circular or conical movement of a limb relative to the horse’s body. During protraction, the limb moves away from the midline before moving back toward it.

Question 7

Descending movement

Answer 7

Downward motion of one or more body parts.

Question 8

Desmitis

Answer 8

Inflammation of ligament tissue.

Question 9

Desmopathy

Answer 9

Ligament disease.

Question 10

Diarthrodial joint

Answer 10

A freely movable joint characterized by the presence of a fibrous capsule, synovial membrane, lubricating (synovial) fluid and fibro- or hylane cartilage layers which line opposing bony surfaces.

Question 11

Excursion

Answer 11

Excessive up and down movement of one or more of the horse’s body parts.

Question 12

Fibrocartilagenous joint

Answer 12

Formed via the presence of an intervertebral disc.

Question 13

Negative palmar/plantar angulation

Answer 13

Abnormal positioning (angulation) of the third phalanx (P3, or coffin, or pedal bone) within the hoof capsule; the front of the bone is elevated relative to the back of the bone and ground surface.

Question 14

Off side

Answer 14

The horse’s right side, also known as the far side.

Question 15

On side

Answer 15

The horse’s left side, also known as the near side.

Question 16

Axial lameness

Answer 16

Altered movement stemming from one or more structures associated with the axial skeleton.

Question 17

Pathognomic

Answer 17

Distinctly peculiar to a specific disease or condition.

Question 18

Sagittal plane

Answer 18

Any plane parallel to the median plane.

Question 19

Synarthrodial joint

Answer 19

A fibrous junction that allows little or no motion between articulating bones.

Question 20

Transverse plane

Answer 20

Passes through the head, body, or limb perpendicular to the part’s long axis.
