Lab exam 2- Concepts 5,7,8 Flashcards
Path of Sperm, eggs, and waste in the Cat/ Rabbit
Sperm Travels- Testes→ Epididymis→ductus deferens→Penis→vulva
Egg Travels- Ovary→ Oviduct→ Uterus
Waste travel from kidney → ureters→ bladder
Components of the pelvic girdle
- Consists of the illia with the illia fused with the vertebrae to stabilize the pelvis ,ischia, and pubis
- Femurs- thigh bones that sits in the acetabulum
- Acetabulum- Depression on either side of the pelvic girdle in which the femur sits
Glottis
Opening into the trachea
Identify the Reproductive structures in the female pigeon
A) Left ovary
B) ostium
C) oviduct
D) Cloaca
E) Ureter
F)Posterior kidney
G) Median kidney
H) Anterior kidney
Keratin adaptations in mammals
use keratin for hair/fur, nails/claws/hooves, and horns
Pancreas
Creates enzymes involved in the digestion of food, and aids in blood sugar control
Epiglottis
The flap that covers the trachea during swallowing so that food does not enter the lungs.
Nails, Claws, Hooves diffrence
Hooves-A hoof is a short, thick structure that surrounds the end of the digit. Claws and Nails are the same but a nail is flat where as a claw is curved
Function of small vs large intestine
Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.
Colic ceca
-Connects to the large intestine in birds and helps in breaking down undigested food.
vertebrae which fuse with the pelvic girdle and fused together to form the sarcum
Sacral vetebrae
Identify Structures A-F
A) Neural Arch
B)Neural Spine
C) Post Zygophoses
D) Transverse process
E) Pre Zygapophyses
F) Centrum
Identify the Reproductive structures in the male pigeon
A) Testis
B) Kidney
C) Vans deferens
D) Ureter
E) Cloaca
the hind part of the stomach, especially modified for grinding food, stores stones or sand that is used to mechanically break down seeds
Gizzard
Support the tail and do not suffer from buckling or torsion
Caudal vertebrate
Lateral protrusions from the nerual arch which support ribs or act as muscle attachment points
Transverse processes
Liver
Processes blood and breaks down nutrients, chemicals, and drugs.
Crop
Adaptation for the pigeon that allows it to store food and produce crop milk
pennaceous feathers vs plumaceous feathers
- pennaceous feather- has barbed structure making them more stiff and used in flight
- plumaceous feathers- soft down feathers that provide warmth
Identify the Reproductive structures in the Male Mudpuppy
A) Archiprhrenic duct
B) Kidney
C) Cloacal gland
D)Cloacal opening
E)Cloacal papillia
F) Urinary bladder
G) Collecting tubles
H) Left testis
I) Ductis efferentes
Two uteri are separate for most of their length but share a single cervix.
Biparte Uterus
Adaptations required for flight
- Forelimbs are modified into wings, humerus and short and bulky and digits are reduced
- Rigid axial and pelvic skeletons allowing stability for centre of gravity during flight.
- pectoral girdle is more robust and the furcula helps store energy for upstrokes
- Keel allows for more muscles to be attached
- Pygostyle allows for control of tail feathers
Flow of food through the Pigeon
Oral cavity→ Esophogus→ Gizzard→Small intestine→ Colic ceca→Large intestine→ cloaca
Toe bones
Phalanges
