Goals for the Term Solid base of knowledge Comfort with Ocular terminology Basics of tissue structure & function At the end of the course you can give yourself a 3D guided tour of the eye and orbit within your mind’s eye.

Exam Schedule & Grading Midterm 37% Lab work sheets & hw (4%) Quizzes: Four each 5.5% (22%) and Final Exam 37% some of Final is review There will be 4 or 5 Lab sessions, attendance is mandatory

Any Questions? How do I get this thing off my finger?

Visual system Overview Let me first remind you that the phototransduction can also take place outside of reconstituted systems. That studying whole cells, tissues and organs will

Overview When the structure seems complicated , think FUNCTION Imaging : OPTICAL CLARITY Information processing: pathways, adaptation Mobility: balance, strength, speed, MECHANICS Biological System: respiration, pain, protection

Terminology Rostral (toward top of head - rooster) Caudal (toward tail) cauda equina - horses tail Anterior - front - ventral Posterior- back - dorsal (dorsal fin) Medial (midline) {Nasal} Lateral away from midline (Temporal) Central - Peripheral- away from center
