Do You Need to Learn the Carpals?

This is one of the hardest groups of bones to commit to memory and you will likely forget it if you don’t use it often.  College professors and some high school anatomy teachers might ask you to learn the bones of the wrist.  The task is made even …

Brain Labeling

  A = cerebrum (parietal lobe) B = gyri (convolutions) C = corpus callosum D = frontal lobe E = thalamus F = hypothalamus G = pituitary gland H = midbrain J = pons K= medulla L = cerebellum (showing arbor vitae) M = transverse fissure N = …

Label the Parts of a Long Bone

    a = epiphysis b = diaphysis c = articular cartilage d = periosteum f = compact bone g = medullary cavity (yellow marrow) h = endosteum j = epiphyseal line (growth plate) Coloring worksheet for this image.  

Brain Dissection, Internal

This video shows the a sagittal cut in the brain of a sheep and identifies the major structures of the brain such as the  cerebrum, corpus callosum, cerebellum, pons, medulla, thalamus, hypothalamus, pineal gland, and the four ventricles.

Pectoral Muscles

  Dissected cat shows the main muscles of the thoracic region:  the pectoantebrachialis, pectoralis major, pectoralis minor and the xiphihumeralis.

Biceps, Lateral and Long Head

The biceps brachii is a two headed muscle on located in the upper arm region.  “Brachii” usually denotes structures found in the upper extremities and “biceps” means that it is a two-headed muscle.  On the cat, if you tease away the fascia you can separate these two heads. …

Large Intestine (Colon)

The large intestine has three main sections which can be difficult to identify in the cat.  Shown below is the abdominal cavity with most of the small intestine removed and the large intestine positioned in such a way to identify the three sections.  The first section after the …

Cecum and Colon

This image shows the jejunum and the ileum as it joins the large intestine (colon).  The pouch at this connection point in the cat is called the cecum.  In humans, the cecum has an attached appendage.   A valve can be found at this point in the digestive …

Stomach and Duodenum

This image shows the stomach and the first section of the small intestine, called the duodenum.  The next section of the small intestine is the jejunum followed by the ileum which connects it to the large intestine.

Jugular Veins, Internal and External

The chest cavity of the cat is opened to reveal the major veins that branch from the heart.  Shown in blue are the superior vena cava, the brachiocephalic, subclavian and the internal and external jugular veins.   

Inferior Vena Cava with Renal Vein

This image shows the inferior vena cava where it branches to the renal vein leading to the kidney.   The vessels appear blue because the cat has been injected with blue latex.

Heart – Coronary Vessels

This image of the heart shows a close-up view of the coronary vessels that are located on its surface.  The cat has been injected with latex to color the vessels (blue for veins, pink for arteries.)  Also visible is the pulmonary artery and the aorta.

Label the Eye

  A = retina | B = choroid | C = sclera | D = cornea E = lens  | F = pupil | G = iris  | H = suspensory ligaments I = optic disk | J = optic nerve | K = fovea centralis (macula) X …

Eye Anatomy

This image shows a dissected cow eye. The vitreous humor has been removed and the retina is visible a thin layer of tissue covering the shiny blue tapetum.  In cows, the tapetum is reflective and helps the animal see in the dark.  (This is also why cow eyes …

Heart – Pulmonary Trunk

The green pin in this heart indicates the pulmonary trunk which will split into the left and right pulmonary arteries.   It is the most anterior vessel of the heart and carries blood from the heart to the lungs where blood becomes oxygenated and returns back to the …

Sheep Brain, External Anatomy

Video shows the major structures:  cerebrum, transverse fissure, longitudinal fissure, superior and inferior colliculi, pineal gland, cerebellum.

Dissection of the Sheep Heart

The vessels of the heart are identified in this video: aorta, pulmonary trunk, brachiocephalic, and the vena cava.  The heart is then cut in half the the internal structures are revealed: the atria,  ventricles, bicuspid and tricuspid.
