Study Notes

Anatomical Regions and Planes

Anatomical regions are specific areas of the body, such as the shoulder, brachial, and antebrachial regions.
Anatomical planes are imaginary two-dimensional planes used to divide the body for descriptive purposes. Examples are the median, dorsal, ventral, and transverse planes.

Terminology and Anatomical Directional Terms

Rostral: Directed toward the nose
Caudal: Directed toward the tail
Ventral: Directed toward the belly
Dorsal: Directed toward the back
Proximal: Closer to the point of attachment
Distal: Farther from the point of attachment
Cranial: Toward the head
Lateral: Away from the midline
Medial: Toward the midline
Palmar/plantar: Relating to the palm or sole, respectively

Skeletal Terminology and Body Regions

Manus: Describing the hand.
Manus = Carpus + Metacarpus + Digits: The manus (hand) comprises the carpus (wrist), metacarpus (palm), and digits (fingers) parts.
Scapula: Shoulder blade
Humerus: Upper arm bone
Radius: Forearm bone on the thumb side
Ulna: Forearm bone on the pinky side
Radius and Ulna: These two bones form the forearm.
Carpal Bones: The wrist bones.
Metacarpal Bones: The bones of the palm.
Phalanges: The bones of the fingers.

Specific Animal Anatomical Differences (Canine, Equine, Bovine)

Equine: Notable differences exist in the scapula (no acromion, enlarged supraglenoid tubercle), humerus (greater tubercle prominent cranial-caudally, intermediate tubercle absent), radius and ulna (fusion, prevents pronation and supination, enlarged olecranon tuber), and manus (separate intermediate and radial carpal bones, fused carpals I+II, three metacarpals, splint bones).
Bovine: The ulna extends the entire length of the forearm.
Canine: Differences exist in various skeletal elements, but details are not exhaustive in the provided text.

Practical Considerations and Anatomical Exceptions

Some anatomical labels are highlighted as exceptions to large animal forelimbs due to variations between species (dog, horse, cow).
Many labels and descriptions are specific to the different skeletal elements in animals.
Variations in species are noted. For example, certain labels are specifically equine or bovine exceptions.

Joints

Various joints are discussed, including the glenohumeral, humeroradioulnar, intercarpal, carpometacarpal, and metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints.
The structure and function of each joint are alluded to, based on information in the provided text.

Muscle Groups

Extrinsic muscles: Muscles originating outside a specific region and acting on another part of the body, such as the trunk (muscles of the neck, back), or the shoulder or limbs.
Intrinsic muscles: Muscles originating and acting within a specific region, such as muscles of the forelimb, shoulder girdle or head.
Information from the text provides a list of extrinsic and intrinsic muscles in the forelimb, like the Brachiocephalicus, Trapezius, Rhomboideus, Serratus Ventralis, and more. Several muscles, such as Biceps brachii, Deltoideus, Supraspinatous, Infraspinatous, Subscapularis, are noted and discussed.

Additional Information

The text also presents various questions related to muscle insertions and anatomical locations, highlighting the practical application and importance of mastering this material.
The detailed text incorporates diagrams that further clarify different areas and perspectives of the limb in relation to various joints and muscles.
