JUST VOCAB AMPHIBIANS Chapters 42 Joining of an egg & sperm outside External fertilization the female’s body ____________________ Kind of development in which offspring are born/hatch looking like their parents only smaller Direct ____________________ development Kind of circulatory system in which blood is contained inside vessels closed __________________ Organism that has a notochord, pharyngeal pouches, a post anal tail, and a dorsal nerve cord ______________________________ Chordate vertebrate Organism with a backbone ____________________ Organism whose blastopore protostome becomes its mouth ____________________ Thin membrane in the coelom that____________________ mesentery connects and holds the internal organs Together Male frog holding onto the female so sperm and eggs amplexus are released together _____________________ Maintaining the correct osmoregulation balance of water and ____________________ ions in the body cranium Covering made of bone that ____________________ protects the brain; also called skull Nerve cord surrounded by bone or cartilage; also called a Spinal cord _____________________ Vertebral column Joining of an egg & sperm inside the female’s body ____________________ Internal fertilization Kind of development in which offspring hatch as larva and must undergo metamorphosis to become adults Indirect ____________________ development Kind of circulatory system in which open blood is NOT contained in vessels __________________ and flows loose inside the coelom 2 Small teeth on the roof of the frog’s mouth that keep prey from escaping Vomerine teeth ______________________ Opening at back of throat for gullet food to enter esophagus ____________________ ileum Coiled portion of small intestine ____________________ between duodenum and large intestine Bile storage organ Lower jaw Gall bladder __________________ mandible ______________________________ maxilla Upper jaw ______________________________ invertebrate Organism without a backbone ____________________ Organism whose blastopore deuterostome becomes its anus ____________________ Eardrum Tympanic membrane __________________ Anura Order of “tail-less” amphibians __________________ including frogs & toads Small out pockets at the anterior end of the digestive tract that become gills in a fish and the throat, ______________________ Pharyngeal pouches inner ears, and tonsils in humans Tail that sticks out past the posterior opening of the digestive Post anal tail tract ____________________ Outside body covering in an animal integument __________________ This kind of body organ works automatically without thinking about it ______________ autonomic The concentration of nervous tissue and sensory organs in the anterior end of an animal cephalization ____________________ In animals the body plan where the left and right sides are mirror images Bilateral symmetry of each other ____________________ This part smoothes the flow of blood leaving the ventricle __________________ Conus arteriosus These small thin walled blood vessels connect arteries and veins and are the place where gases, wastes, & nutrients are exchanged __________________ capillaries arteries Blood vessels that carry blood ________________________ away from the heart Membrane that covers and protects Nictitating membrane a frog’s eye while swimming ______________________ Area in a fish’s brain that receives and processes info from visual, auditory, Optic tectum and lateral line systems _______________________________ Posterior part of the brain that controls balance and muscle coordination ________________________ cerebellum Blood vessels that carry blood back to the heart veins _________________ Vertebral Nerve cord surrounded by bone or Cartilage; also called a spinal cord _________________ column Posterior part of the brain that integrates Info from the other brain parts and where Higher brain functions like memory, learning, cerebrum Reasoning, and problem solving occur _____________ Collecting chamber that receives blood returning to the heart from the body Before it enters the atrium __________________________ Sinus venosus Part of the brain that controls the autonomic internal organs __________________________ Medulla oblongata and relays sensory info from body The concentration of nervous and sensory organs in the anterior end of an animal _____________________________ cephalization Small fingerlike extensions inside the intestine that increase surface area villi for greater absorption of nutrients _______________ First section of intestine _______________________ duodenum nearest stomach The energy molecule is stored in the liver ________________________ glycogen This substance is made by the pancreas and causes cells to release glucose into glucagon the bloodstream. __________________ (Be careful! It sounds like the answer above. Don’t get these 2 confused!) Order of “leg-less” amphibians APODA Including caecilians ____________________ Multipurpose exit space before cloaca the vent ____________________ Body temperature that is dependent on their environment “cold-blooded” ectothermic __________________ The changing from a larva into the adult form ______________________________ metamorphosis Tubules that carry eggs from ____________________ oviducts ovary to cloaca & add the jelly coating Order of amphibians with tails Urodela including newts & salamanders ____________________ Exit opening in animals with vent a cloaca __________________ Opening at back of mouth to glottis the lungs ____________________ nares Scientific name for “nostrils” ____________________ olfactory Sense that deals with smell____________________ Circulation that carries blood pulmonary from heart to lungs and back to heart__________________ Urine storage organ Urinary bladder _________________________ Circulation that carries blood from heart systemic to body organs and back to heart ____________________
