VBSC 421 Exam 1
Amphicoelous - ANS-centra with concave surfaces at either end at either end
characteristic of fish, amphibians, some reptiles
Procoelous - ANS-vertebrae with anterior concave and posterior convex articulating
surfaces
Opisthocoelous - ANS-possess anterior convex and posterior concave articulating
surfaces
many amphibians and early reptiles
Heterocoelous - ANS-centrum with saddle shaped posterior end that articulates with an
appropriately concave anterior end of an adjacent vertebra
Basal Plate (shark) - ANS-chondrocranium
posterior to basitrabecular process
Branchial Arches (shark) - ANS-Splanchnocranium
skeletal support for the gills, surrounds the pharynx
Carotid Foramen (shark) - ANS-Chondrocranium
carotid arteries pass through
Ceratohyal cartilage (shark) - ANS-splanchoncranium
angle of the jaws
epiphyseal foramen (shark) - ANS-chondrocranium
pineal organ originates from
eye orbits (shark) - ANS-chondrocranium
houses the eyeballs
foramen magnum (shark) - ANS-chondrocranium
spinal cord passes through
Gill rakers (shark) - ANS-splanchnocranium
strain for food to avoid getting it into the respiratory tract
