- This page explores the anatomy and functions of the eyes and ears, essential for vision, hearing, and balance. It details the structure of the eye, its accessory features, and the components of the outer, middle, and inner ear. The anatomy of the spiral organ of Corti and its involvement in hearing is also highlighted. The overall goal is to enhance comprehension of how these sensory organs capture stimuli and the brain's interpretation of this information.
- 10.2: Eye Anatomy
- This page outlines the internal anatomy of the eye, detailing its three layers: the fibrous layer for support, the vascular layer for blood supply, and the neural layer (retina) for light detection. It describes the retina's photoreceptors (rods for low-light vision and cones for color vision), the role of bipolar cells in relaying signals, and the optic nerve's connection to the brain. Additionally, it covers key structures such as the sclera, cornea, and components of the retina.
- 10.3: Cow Eye Dissection
- This page details the cow eye dissection process, stressing safety and the use of personal protection equipment (PPE) and tools. It provides a step-by-step guide, requiring students to label key structures like the sclera, cornea, and retina, while noting the absence of the tapetum lucidum in humans. The page emphasizes proper disposal and maintaining equipment cleanliness as crucial elements of the dissection.
- 10.4: Ear Anatomy
- This page provides an overview of ear anatomy, highlighting its three main sections: the outer ear (auricle and external acoustic meatus), middle ear (tympanic membrane and auditory ossicles), and inner ear (cochlea, vestibule, and semicircular canals).
- 10.5: Microscope Slides - Eyes and Ears
- This page describes a laboratory exercise where students observe and photograph the anatomy of the eye and cochlea using microscopes. They start with a dissecting microscope to capture images of the anterior eye, identifying structures like the lens and iris. Then, they examine the posterior eye at 400x magnification to label the retina and photoreceptors.
- 10.6: Questions and Review - Eyes and Ears
- This page focuses on labeling the anatomical structures of the eye and ear, utilizing visual aids and word banks. Students are tasked with identifying parts like the cornea, iris, retina, cochlea, and tympanic membrane. The exercise aims to improve understanding of anatomical terminology and the functions of these sensory organs.
