Study Notes
Major Muscles of the Canine Body
-
Masseter: Key muscle in the cheek area responsible for closing the jaw, essential for chewing.
-
Brachiocephalic: Muscle connecting the upper arm and head; facilitates the extension of the head and neck while pulling the thoracic limb forward.
-
Latissimus dorsi: Long, superficial dorsal muscle; attaches the humerus to the lumbar region, playing a crucial role in shoulder joint flexion.
-
Trapezius: Triangular shoulder muscle primarily involved in neck extension.
-
External abdominal oblique: Large flat muscles supporting digestive and reproductive organs; compresses abdominal wall and aids in lateral trunk rotation.
-
Gluteals: Prominent muscles of the upper hindquarters (buttocks); crucial for hip joint extension.
-
Quadriceps femoris: Large muscle group located on the front of the thigh; primarily responsible for extending the stifle (knee).
-
Semitendinosus: Part of the hamstring group; functions in extending the thigh and flexing the leg.
-
Gastrocnemius: Calf muscle that extends the hock (ankle) and helps in toe pointing; resembles the shape of the stomach.
-
Biceps femoris: Lateral superficial muscle of the hamstring group; contributes to hip extension and stifle flexion.
-
Intercostal: Muscles located between the ribs; facilitate rib movement during breathing.
-
Pectoral: Major chest muscles involved in the adduction of the thoracic limb, playing a vital role in fore limb movement.
-
Deltoid: Shoulder muscle causing leg abduction and flexion of the shoulder joint; named for its resemblance to the Greek letter 'delta' Δ.
-
Triceps brachii: Extends the elbow joint during contraction, crucial for straightening the arm.
-
Biceps brachii: Muscle responsible for flexing the elbow joint, allowing the arm to bend.
-
Serratus ventralis: Significant muscle connecting the front legs to the body; vital for attaching the forelimb to the trunk, enhancing mobility.
