Fish anatomy Flashcards
dentary teeth
teeth attached to the dentary
Mandible
lower jaw
Pineal organ?
may detect light and may affect the distribution of skin pigments and reproductive behaviour
Branchial basket?
surrounds gills and heart
tongue
Gall Bladder?
small pouch that sits just under the liver. stores bile produced by the liver.
Buccall funnel
a circular, sucker like mouth fringed with cilia called buccal papillae and containing tooth like organs (keratinized teeth)
sinus venosus?
the first chamber of the heart that empties into the atrium
atrium?
pumps blood into the ventricles
palatal teeth
teeth on the palate
esophagus
carries food to the stomach
gill slits?
any of a series of openingings between the gill arches of a fish, through which water passes from the pharynx to the exterior, bathing the gills in the process
Bile duct?
the bile ducts carry bile from the liver and gallbladder through the pancrease to the duodenum which is a part of the small intestine.
Pancrease?
is an organ located in the abdomen and it plays an essential role in converting food we eat into fuel for the bodys cell.
ventricle?
pumps blood into the arteries
Notochord?
unconstructed support of main longitudinal skeleton
Branchial tube?
contains the seven gill slits
claspers:
an external appendage found on male sharks, skate and rays that are designed to deliver sperm inside of a female
Operculum:
is the bony flap covering and protecting the gills
premaxillary teeth
teeth on the premaxilla
epaxial
muscle situated on the dorsal side
transverse septum?
seperating the epaxial and hypaxial muscle
palate?
the roof of the mouth, seperating the cavities of the nose and the mouth in vertebrates
pyloric-caeca
are finger like projections located in the stomach of many fish species. The pyloric saeca seceret digestive enzymes and increase the surface area in the stomach for nutrient absorption
quiz yourself on the paper one too! remember that lingual cartilege is like right behind the tongue and the lingual muscke behind that! and remember heart is right before liver
olfactory sac?
enables smell
Liver?
the livr plays a central role in all metabolic processes in the body
Lateral line?
is a system of sense organs used to detect movement, vibration and pressure gradients in the surrounding water.
swim bladder?
a gas filled sac found in many bony fish that helps maintain bouyancy
Spiracle:
special gill slits located just behind the eyes. They supply oxygen directly to the eyes and brain of the shark
Buccal papillae:
has a sensory function and reinforces suction
myomeres?
muscle fibers folded into a complex W shaped configuration, facilitates movement
and rostrum is the nose!
conus arteriosus?
primary function is to prevent the backflow of blood and keep a steady flow of blood into the ventral aorta and the gills.
maxillary teeth
teeth on the maxilla
buccal pappilae
the pharynx in the lamprey is supported by what?
lingual cartilege and muscle
Maxilla
upper jaw
myosepta?
connective tissue
missing is the ovary and bile duct which is also under the liver!
hypaxial
muscle situated on the ventral side
