Study Notes
Lung Structure
- Left lung consists of cranial and caudal lobes.
- Right lung has cranial, middle, and caudal lobes.
- Some variations exist, such as the presence of an accessory lobe in the right lung.
Kidney Structure in Horses
- Horse kidneys exhibit unique shapes: the right is heart-shaped and the left is bean-shaped.
- Abnormal shapes, like irregularly oval and lobated, are also observed.
Mare's Ovaries
- The bean-shaped appearance of a mare's ovaries is attributed to the ovulation fossa, a specific region important for ovulation.
Uterine Characteristics in Domestic Animals
- Pigs have a uterus characterized by long cervix and short body with long horns.
- Uterus develops from paramesonephric ducts, similar to salpinx and vagina.
- Cervical folds vary by species: longitudinal in mare, cat, and dog; circular in pig; interdigitating in cow.
- Uterine wall features caruncles for attachment of embryonic cotyledons during pregnancy.
Pancreatic Duct Structures
- Domestic animals present varied pancreatic duct structures, which are crucial for accurate veterinary diagnosis.
Growth Plate Ossification
- Cattle growth plates completely ossify by 20 months of age.
Pancreas Functions
- The pancreas' primary endocrine functions reside in the Islets of Langerhans.
- Beta cells secrete insulin in response to hypoglycemia.
- D cells inhibit secretions from Alpha and Beta cells.
- Digestive enzymes are produced by pancreatic acinar cells.
Liver Phagocytic Cells
- Kupffer cells are the primary phagocytic cells found in the liver.
Endothelium
- Special simple squamous epithelium lining blood vessels, including the heart, is known as endothelium.
Red Blood Cell Size
- Caprine species have the smallest average size of red blood cells compared to equine, canine, and bovine species.
Ovarian Structure in Domestic Animals
- In most domestic animals, the cortex is peripheral and the medulla is central.
- Sows are unique as their cortex and medulla are arranged in reverse.
Estrous Cycle Stages in Bitches
- Vaginal cytology with cornified cells and pyknotic nuclei indicates the estrus stage.
Ovarian Follicle Events Sequence
- The correct sequence of ovarian follicle development is Graafian follicle > corpus luteum > corpus hemorrhagicum.
Heart Conditions in Pigs
- Ascites in piglets often suggests right side heart failure is the most affected area.
Rodent Uterus Structure
- Rodent and rabbit uteri are characterized by completely separated uterine horns and separate cervices, described as duplex.
Ruminant Dental Formula
- Ruminants typically have a dental formula of 0/3, 0/1, 3/3, 3/3.
Chicken Digestive System
- Chickens possess a proventriculus, which is the true stomach where digestive enzymes are secreted.
Chicken Oviduct Shell Gland
- The uterus, part of the chicken oviduct, is responsible for adding the shell to the egg.
Lack of Seminal Vesicles
- Cats and horses lack seminal vesicles, while cattle and goats possess them.
Notocord Derivatives
- The intervertebral disc arises from the notochord during embryonic development.
Cattle Placentation
- Cattle exhibit multicotyledonary, syndesmochorial placentation patterns and are classified as deciduate.
Embryonic Cleaving Events
- Cleavage refers to embryonic mitotic division where total size remains constant across daughter cells.
