Fetal Pig Dissection Anatomy and Physiology

A comprehensive set of vocabulary flashcards covering the anatomical features, locations, and functions required for a fetal pig dissection.

Urogenital opening

The opening where the reproductive and urinary systems exit the body, present in both male and female fetal pigs.

Genital papilla

A small, fleshy projection found near the urogenital opening specifically in female fetal pigs.

Sex of the fetal pig

Determined by identifying external features such as the genital papilla or the location of the urogenital opening.

Hard palate

The bony, ridged anterior portion of the roof of the mouth.

Soft palate

The fleshy, smooth posterior portion of the roof of the mouth.

Trachea

The windpipe; a ribbed tube that leads from the throat to the lungs for air transport.

Esophagus

The muscular food tube that connects the throat to the stomach.

Stomach

A large sac-like organ in the abdominal cavity responsible for the primary stages of digestion.

Spleen

An elongated, flattened organ located near the stomach.

Large intestine

Part of the digestive system also known as the spiral colon in the fetal pig.

Spiral colon

The specifically coiled portion of the large intestine found in the fetal pig.

Urinary bladder

An organ that stores urine before it is expelled from the body.

Urethra

The tube that carries urine from the urinary bladder to the outside of the body.

Uterus

The reproductive organ in female pigs where offspring develop.

Penis

The male reproductive organ used for excretion and reproduction.

Testes

The male reproductive organs responsible for producing sperm.

Anatomy

The study of the structure of the fetal pig as identified during dissection.

Physiology

The study of the function of the organs and systems within the fetal pig.

Location: Male Urogenital Opening

Found on the ventral surface of the pig, just posterior to the umbilical cord.

Location: Female Urogenital Opening

Found just ventral to the anus.

Structure and Function

The dual focus of the fetal pig dissection lab requirements.

Anatomical Identification

The process of locating and naming specific features like the trachea or esophagus.

Fetal Pig Dissection

A laboratory exercise used to study the internal and external anatomy of a specimen.

Oral Cavity Roof

Comprised of two distinct parts: the hard palate and the soft palate.

Respiratory Tube

Refers to the trachea during the identification process.

Digestive Tube

Refers to the esophagus during the identification process.

Digestive Sac

Refers to the stomach, a primary organ for food storage and breakdown.

Coiled Digestive Organ

Refers to the spiral colon or large intestine.

Waste Storage

The primary function of the urinary bladder.

Urinary Pathway

The route urine takes through the bladder and the urethra.

Female Specimen Identification

Confirmed by the presence of a genital papilla.

Male Specimen Identification

Confirmed by locating the urogenital opening near the umbilical cord.

Trachea Structure

Characterized by cartilaginous rings that keep the airway open.

Soft Palate Location

Situated posterior to the hard palate in the mouth.

Urogenital System (Male)

Includes structures such as the penis and testes.

Urogenital System (Female)

Includes structures such as the uterus and genital papilla.

Digestive System Components

Includes the esophagus, stomach, and large intestine (spiral colon).
