Sagittal Plane: Any plane parallel to the median plane. For instance, a plane dividing the right and left sides of a hoof.

Sensory Nerves: Nerves that serve to carry sensory information to the brain for processing.

Sheath: A “sleeve” that envelops tendons as they course over or under joint surfaces.

Solar Surface: The (bottom) aspect of the foot that contacts the ground surface.

Speedy Cutting: Striking the hind limb with a forefoot. Usually observed in disciplines that entail making sharp turns at high speeds (e.g. barrel racing and cutting).

Stance: The phase of a horse’s stride during which the respective limb is in contact with the ground surface.

Stay-Apparatus: An arrangement of muscles, tendons, and ligaments that work together to “lock” major joints of a limb in the extended position. The horse enjoys stay-apparatuses in both the fore and hind limbs, thereby allowing it to remain standing with minimal muscular effort. The mechanism is transiently employed during locomotion and fully employed during periods of upright sleep.

Striking: Contacting a limb with a hoof.

Subacute: Of fairly recent onset. “This is a subacute lameness; it developed last Tuesday.”

Subluxated: Partial dislocation or displacement of one object (usually bone) relative to another.

Suspensory Desmitis: Inflammation of the suspensory ligament body and/or its branches.

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

Syndesmodic Joint: An immovable joint in which bones are joined by dense connective tissue.

Synovial: Associated with a joint, tendon sheath, and/or bursa (which are all synovial structures).
