Fetal Pig Dissection

A study of the anatomy of a fetal pig used for educational purposes.

Anatomic Position

A standard position of the body used as a reference in anatomy, standing upright, facing forward, arms at the sides with palms facing forward.

Dissection

To expose and view the internal structures of an organism, rather than simply cutting into it.

Connective Tissue

A type of tissue that supports, binds, or separates other tissues and organs in the body.

Origin (of muscle)

The attachment point of a muscle on a bone that remains stationary during muscle contraction.

Insertion (of muscle)

The attachment point on the bone where the muscle causes movement during contraction.

Proximal

A position closer to the trunk of the body.

Distal

A position further away from the trunk of the body.

Dorsal

The side of the body nearest the backbone.

Ventral

The side of the body nearest the belly.

Adductor

A muscle that draws a part toward the midline of the body.

Extensor

A muscle that increases the angle between body parts, such as straightening a limb.

Safety Equipment

Protective gear such as gloves, lab coats, and goggles used during dissection.

Mammary Papillae

Nipple-like structures on the abdomen of both male and female pigs, indicating potential for milk production in females.

Urogenital Opening

The external opening for the urinary and reproductive tracts, differing in males and females.

Deltoid Muscle

A shoulder muscle that raises the humerus, originating from the scapula.

Biceps Muscle

A flexor muscle that allows for the bending of the elbow.

Triceps Muscle

An extensor muscle located at the back of the arm, responsible for straightening the elbow.

Dissection Tray

A flat container used to hold dissection specimens while performing dissections.

Carolina's Perfect Solution®

A nontoxic chemical solution used for preserving specimens, though it has a strong smell.

Fetal Pig Gender Identification

The ability to determine if a fetal pig is male or female by identifying anatomical features.
