Issues that Affect Performance Course
Section 1 Learning Activity - Definitions The following definitions are taken from the book “Equine Lameness for the Layman” by Dr. Robert Grisel
2
Amphiarthrodial Joint
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Amphiarthrodial Joint
3
Amphiarthrodial Joint
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Amphiarthrodial Joint A fibrocartinagenous junction that allows limited motion between articulating bones. Examples: The junction between the pubic bones of the pelvis. The articulation between the first pair of ribs and the sternum.
4
Ascending Movement Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Ascending Movement
5
Ascending Movement Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Ascending Movement Upward motion of one or more body parts. Example: the up and down motion of the top of the hip when the horse is walking.
6
Axial Skeleton Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Axial Skeleton
7
Axial Skeleton Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Axial Skeleton Consists of the horse’s head, vertebral column, and sacrum
8
Axial Lameness Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Axial Lameness
9
Axial Lameness Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Axial Lameness Altered movement stemming from one or more structures associated with the axial skeleton. Temporomandibular synovitis (TMJ), cervical arthrosis and “kissing spines” all have the potential to generate axial lameness in the horse.
10
Biomechanical Lameness
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Biomechanical Lameness
11
Biomechanical Lameness
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Biomechanical Lameness Altered movement(s) made in an attempt to accommodate restricted or exaggerated action of one or more parts of the horse’s anatomy (usually the limbs). Many forms of biomechanical lameness have no inflammatory component and accordingly do not hurt.
12
Circumduction Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Circumduction
13
Circumduction Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Circumduction The circular or conical movement of a limb relative to the horse’s body. During protraction, the circumducting limb moves away from the midline before moving back toward it, thus tracing a semicircle. This gait deficit is most often associated with neurologic disease in the horse.
14
Descending Movement Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Descending Movement
15
Descending Movement Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Descending Movement Downward motion of one or more body parts.
16
Desmitis Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Desmitis
17
Desmitis Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Desmitis Inflammation of ligament tissue.
18
Desmopathy Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Desmopathy
19
Desmopathy Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Desmopathy Ligament disease.
20
Diarthrodial Joint Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Diarthrodial Joint
21
Diarthrodial Joint Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Diarthrodial Joint A freely-movable joint characterized by the presence of a fibrous capsule, synovial membrane, lubricating (synovial) fluid and fibro- or hyaline cartilage layers which line opposing surfaces. Examples: The elbow joint and stifle joint.
22
Excursion Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Excursion
23
Excursion Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Excursion Excessive up-and-down movement of one or more of the horse’s body parts.
24
Fibrocartilagenous Joint
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Fibrocartilagenous Joint
25
Fibrocartilagenous Joint
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Fibrocartilagenous Joint Formed via the presence of an intervertebral disc.
26
Negative palmar/plantar angulation
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Negative palmar/plantar angulation
27
Negative palmar/plantar angulation
Issues that Affect Performance Course Section 1 Learning Activity - Definitions Negative palmar/plantar angulation Abnormal positioning (angulation) of the third phalanx (aka P3, 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. Palmar refers to the front hoof, plantar refers to the hind hoof.
28
Off side Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Off side
29
Off side Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Off side The horse’s right side, also known as the far side.
30
On side Issues that Affect Performance Course
Section 1 Learning Activity - Definitions On side
31
On side Issues that Affect Performance Course
Section 1 Learning Activity - Definitions On side The horse’s left side, also known as the near side.
32
Pathognomic Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Pathognomic
33
Pathognomic Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Pathognomic Distinctly peculiar to a specific disease or condition.
34
Sagittal Plane Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Sagittal Plane
35
Sagittal Plane Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Sagittal Plane Any plane parallel to the median plane. For instance, a plane dividing the right and left sides of a hoof.
36
Synarthrodial Joint Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Synarthrodial Joint
37
Synarthrodial Joint Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Synarthrodial Joint A fibrous junction that allows little or no motion between articulating bones. Examples: The attachment of the splint bone to the cannon bone. The attachment of the bone plates in the horse’s skull.
38
Transverse Plane Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Transverse Plane
39
Transverse Plane Issues that Affect Performance Course
Section 1 Learning Activity - Definitions Transverse Plane Passes through the head, body, or limb perpendicular to the part’s long axis. This plane would be different depending upon which body part you were discussing.
