9 Questions
Match the following terms with their definitions/functions:
ossicles = tiny calcareous elements embedded in the dermis of the body wall madreporite = porous stone pore opening to water vascular system pedicellariae = jaw-like pincers which respond to touch, food and other stimuli or keep the outer surface clean ring canal = water vascular canal which surrounds oesophagus
Match the following terms with their definitions/functions:
stone canal = water vascular canal connecting madreporite to ring canal radial canal = water vascular canal radiating from ring & bear tube feet Tiedmann's bodies = produce coelomic amebocytes (corpuscles) to destroy waste, bacteria Polian vesicles = store excess water
Match the following terms with their definitions/functions:
ampulla = store water to effect movement or extension of tube feet tube feet = tube-like hydraulic projections as part of the water-vascular system used for locomotion water vascular system = hydraulic circulatory system which operates the tube feet and facilitates respiration ambulacral groove = linear depression over the radial canals in which tube feet may be located.may be open (only covered by epidermis rather than dermis and ossicles) or closed.
Match the following structures with their descriptions:
Notochord = Rod-shaped mid-dorsal rod of mesodermal cells enclosed in fibrous sheath which bends without shortening to support the body and anchor muscles Endostyle = Endodermal structure which secretes mucus which traps food brought into the pharyngeal cavity Post anal tail = Muscular appendage after the anus for locomotion and balance Proboscis = Anterior extensible tubular structure used to secrete mucus and probe for food
Match the following terms with their meanings:
Cephalization = The mouth, sense organs, and nerve ganglia become concentrated at the front end of an animal, producing a head region Dentine = Hard calcareous tissue (harder than bone) Integument = Outer protective area (skin) Eustachian tube = Canal from middle ear to nasopharynx which equalizes pressure between middle ear and outside
Match the following anatomical features with their functions:
Pharyngeal gill slits = Openings in the pharynx for filter feeding and that become gill arches Occipital condyle = Point at which vertebral column is attached to the skull Pectoral girdle = Appendicular skeleton which connects to the forelimb Epidermis = The surface epithelium of the skin, overlying the dermis
Match the following organisms with their classification:
Chordata = Animalia with notochord at some stage of development Hemichordata = Echinoderms with tentacle-like structures surrounding the buccal cavity Urochordata = Echinoderms/ Asteroidea Cephalochordata = Echinoderms/ Ophiuroidea
Match the following terms with their definitions:
Fissiparity = Animal actively divides and re-grows each part of the body Tetrapod = Having 4 limbs Pelvic girdle = Appendicular skeleton which connects to the hind limb Bone = Connective tissue consisting of osteocytes embedded in a matrix of collagen and inorganic minerals and has a blood supply
Match the following structures with their compositions:
Cartilage = Connective tissue consisting of chondrocytes embedded in a matrix of collagen Muscles = Structure of ossicles, teeth, and muscles which scrapes food Tunic = Outer covering serving as exoskeleton Dermis = The thick layer of living tissue below the epidermis containing blood capillaries, nerve endings, sweat glands, hair follicles
