Study Notes

Muscles of the Cat

Pectoantebrachialis: Runs straight across the chest; originates from the manubrium of the sternum and inserts at the superficial fascia of the elbow.
Pectoralis Major: Forms a triangle beneath the pectoantebrachialis; originates from the sternum and clavicle, inserting at the humerus.
Pectoralis Minor: Smaller triangular muscle below the pectoralis major; originates from ribs 3, 4, and 5 and inserts at the scapula.
Xiphihumeralis: Located lateral and inferior to the pectoralis minor; originates from the xiphoid process of the sternum and inserts at the humerus.
Sternomastoid: Neck muscle under the sternohyoid and next to the clavotrapezius; originates from the sternum and inserts at the mastoid process.
Clavotrapezius: Dorsal and lateral neck muscle; originates from the occipital bone and inserts at the clavicle.
Spinotrapezius: Located dorsally and superior to the latissimus dorsi; originates from thoracic and lumbar vertebrae, inserting at the scapula.
Latissimus Dorsi: Positioned on the dorsal side, inferior to the spinotrapezius; originates from lumbar vertebrae and iliac crest, inserts at the humerus.
External Obliques: On the lateral stomach region, inferior to the xiphihumeralis; originates from posterior ribs and lumbodorsal fascia, inserts at the pelvic girdle, linea alba, and midventral raphe of the thorax.
Rectus Abdominis: Medial to the external obliques, beneath the xiphihumeralis; originates from the pubis and inserts at the sternum and costal ribs.
Spinodeltoid: Lateral to the acromiotrapezius and above the latissimus dorsi; originates from the scapula’s spine and inserts at the deltoid ridge of the humerus.
Acromiodeltoid: Above the spinodeltoid and below the clavotrapezius; originates from the acromion process of the scapula and inserts at the spinodeltoid.
Sternohyoid: Located in the neck, above and medial to the sternomastoid; originates from the first costal rib and inserts at the body of the hyoid bone.
Sternothyroid: Above the sternomastoid, lateral to the sternohyoid; originates from the first costal rib and inserts at the thyroid cartilage.
Mylohyoid: Above the sternohyoid and medial to the sternothyroid; originates from the mandible and inserts at the median raphe.
Digastric: Positioned above and lateral to the mylohyoid; originates from the jugular and mastoid processes and inserts at the mandible.
Masseter: Side of the face, anterior to the parotid gland; originates from the zygomatic arch and inserts at the mandible.
Epitrochlearis: Thin muscle on the medial humeral surface, superficial to other muscles; originates from the latissimus dorsi and inserts at the olecranon process.
Triceps Brachii (long head): Deep muscle beneath the epitrochlearis; originates from the axillary border of the scapula and inserts at the olecranon process.
Triceps Brachii (medial head): Located above the long head; originates from the humerus and inserts at the olecranon process.
Biceps Brachii: Above the long head of the triceps; originates from the glenoid fossa and inserts at the radius.
Flexor Carpi Ulnaris: On the ulna, beneath the palmaris longus; originates from the medial epicondyle of the humerus and olecranon process and inserts at the pisiform.
Palmaris Longus: Above the flexor carpi ulnaris; originates from the medial epicondyle of the humerus and inserts at the phalanges.
Brachioradialis: Anterior flexor muscle; superior to the flexor carpi radialis; originates from the middle fifth of the humerus and inserts at the styloid process of the radius.
Flexor Digitorum Profundus: Deep and above the palmaris longus; originates from the ulna and humerus and inserts at the basal phalanges.
Flexor Carpi Radialis: Above the flexor digitorum profundus; originates from the medial epicondyle of the humerus and inserts at the second and third metacarpals.
Pronator Teres: Triangular muscle; located between several forearm muscles; originates from the medial epicondyle of the humerus and inserts at the medial surface of the radius.
Brachialis: Above the lateral head of the triceps; originates from the humerus and inserts at the ulna.
Extensor Carpi Radialis Longus: Located dorsal to the brachioradialis; originates from the lateral supracondylar ridge of the humerus and inserts at the second metacarpals.
