Fetal Pig Glossary
Abdomen - The
part of the body that lies between the thorax and the pelvis and encloses the
stomach, intestines, liver, spleen, and pancreas. Also called belly.
- the opening at the end of the digestive system from which
feces (waste) exits the body.
- a small sac located on the cecum.
the part of the large intestine that run upwards; it is located after the cecum.
Atrium - A
bodily cavity or chamber, especially either of the upper chambers of the heart
that receives blood from the veins and forces it into a ventricle. In this
sense, also called auricle.
- a digestive chemical that is produced in the liver, stored
in the gall bladder, and secreted into the small intestine.

pouch forming the beginning of the large intestine. In this sense, also called
blind gut. Called the appendix in Humans.
convolutions - The
wrinkled outer surface of the cerebrum and the cerebellum.
The large, rounded
structure of the brain occupying most of the cranial cavity, divided into two
cerebral hemispheres that are joined at the bottom by the corpus callosum. It
controls and integrates motor, sensory, and higher mental functions, such as
thought, reason, emotion, and memory.
area - Of or
relating to a neck or a cervix.
- food in the stomach that is partly digested and mixed with
stomach acids. Chyme goes on to the small intestine for further digestion.
vein - Any one of
the veins that drains blood from the muscular tissue of the heart and empties
into the coronary sinus.
Cranium - The
portion of the skull enclosing the brain; the braincase.
duct - The duct that
conveys bile from the gallbladder to the common bile duct.
the part of the large intestine that run downwards after the transverse colon
and before the sigmoid colon.
- A muscular
membranous partition separating the abdominal and thoracic cavities and
functioning in respiration.
portion of the small intestine; it is C-shaped and runs from the stomach to the
- The thin elastic
cartilaginous structure located at the root of the tongue that folds over the
glottis to prevent food and liquid from entering the trachea during the act of
- The muscular,
membranous tube for the passage of food (via peristalsis) from the pharynx to the stomach; the gullet.
Any of the soft
membranous gaps between the incompletely formed cranial bones of a fetus or an
infant. Also called soft spot.
bone - A cranial
bone consisting of a vertical portion corresponding to the forehead and a
horizontal portion that forms the roofs of the orbital and nasal cavities.
a small,muscular, sac-like organ located near the duodenum. It stores and
releases bile (a digestive chemical which is produced in the liver) into the
Glottis - The
opening between the vocal cords at the upper part of the larynx.
palate - The
relatively hard, bony anterior portion of the palate.
duct - The main
excretory duct of the liver, which joins the cystic duct to form the common bile
valve - The
sphincter valve between the ileum portion of the small intestine and the large
Ileum - The
terminal portion of the small intestine extending from the jejunum to the cecum (just
before the large intestine begins).
- the long, coiled mid-section of the small intestine; it is
between the duodenum and the ileum.
Kidney - Either
one of a pair of organs in the dorsal region of the vertebrate abdominal cavity,
functioning to maintain proper water and electrolyte balance, regulate acid-base
concentration, and filter the blood of metabolic wastes, which are then excreted
Larynx - The
part of the respiratory tract between the pharynx and the trachea, having walls
of cartilage and muscle and containing the vocal cords enveloped in folds of
- a large organ located above and in front of the stomach. It
filters toxins from the blood, and makes bile (which breaks down fats) and some
fissure - The
diersion between the right and left hemisphere of the brain.
The lower jaw of a
- Any of several
folds of the peritoneum that connect the intestines to the dorsal abdominal
wall, especially such a fold that envelops the jejunum and ileum.
- the first part of the digestive system, where food enters the body. Chewing
and salivary enzymes in the mouth are the beginning of the digestive process
(breaking down the food).
opening - Passageway
between the oralpharynx (throat) and the nasopharynx (nasal cavity).
Palate - The
roof of the mouth in vertebrates having a complete or partial separation of the
oral and nasal cavities and consisting of the hard palate and the soft palate.
A long, irregularly
shaped gland in vertebrates, lying behind the stomach, that secretes pancreatic
juice into the duodenum and insulin, glucagon, and somatostatin into the
- an enzyme-producing gland located below the stomach and
above the intestines. Enzymes from the pancreas help in the digestion of
carbohydrates, fats and proteins in the small intestine.
bone - Either of two
large, irregularly quadrilateral bones between the frontal and occipital bones
that together form the sides and top of the skull.
- The membranous sac
filled with serous fluid that encloses the heart and the roots of the aorta and
other large blood vessels.
- rhythmic muscle movements that force food in the esophagus from the throat
into the stomach. Peristalsis is involuntary - you cannot control it. It is also
what allows you to eat and drink while upside-down.
- The serous
membrane that lines the walls of the abdominal cavity and folds inward to
enclose the viscera.
artery - An artery
that carries venous blood from the right ventricle of the heart to the lungs.
valve - Sphincter
muscle between the stomach and the duodenum.
- the lower part of the large intestine, where feces are
stored before they are excreted.
glands located in the mouth that produce saliva. Saliva contains enzymes that
break down carbohydrates (starch) into smaller molecules.
the part of the large intestine between the descending colon and the rectum.
palate - The movable
fold, consisting of muscular fibers enclosed in mucous membrane, that is
suspended from the rear of the hard palate and closes off the nasal cavity from
the oral cavity during swallowing or sucking.
process - The long
rearward projection from the arch of a vertebra that provides a point of
attachment for muscles and ligaments.
Spleen - A
large, highly vascular lymphoid organ, lying in the human body to the left of
the stomach below the diaphragm, serving to store blood, disintegrate old blood
cells, filter foreign substances from the blood, and produce lymphocytes.
Sternum - A
long flat bone in most vertebrates that is situated along the ventral midline of
the thorax and articulates with the ribs. The manubrium of the sternum
articulates with the clavicles in human beings and certain other vertebrates.
Also called breastbone.
- a sack-like, muscular organ that is attached to the esophagus. Both chemical
and mechanical digestion takes place in the stomach. When food enters the
stomach, it is churned in a bath of acids and enzymes.
cavity - Chest
cavity including the heart, lungs, thachea, area between the neck region and the
Gland - Gland
located on the upper area of the heart.
gland - A two-lobed
endocrine gland found in all vertebrates, located in front of and on either side
of the trachea in human beings, and producing various hormones, such as
triiodothyronine and calcitonin.
Trachea - A
thin-walled tube of cartilaginous and membranous tissue descending from the
larynx to the bronchi and carrying air to the lungs. Also called windpipe.
the part of the large intestine that runs horizontally across the abdomen.
process - A process
projecting outward from the side of a vertebra.
muscle - Either of
two large, flat, triangular muscles running from the base of the occiput to the
middle of the back that support and make it possible to raise the head and
cord - The flexible
cordlike structure connecting a fetus at the navel with the placenta and
containing two umbilical arteries and one vein that transport nourishment to the
fetus and remove its wastes.
