Study Notes
Optic Radiation and Eye Development
- The optic radiations are also known as the Geniculo-calcarine tract.
- The developing ear arises at the level of the rhombencephalon.
- The development of the eye is derived from surface ectoderm, neural crest cells, and neuroectoderm.
Anatomy of the Eye
- The tectorial membrane is a pointed structure.
- The Meissner's corpuscle is a pointed structure.
- The external stratified squamous epithelium layer of the cornea assists in the renewal of corneal abrasion.
Auditory Pathway
- N3 of the auditory pathway involves the Ipsilateral and contralateral trapezoid body + Superior olivary nucleus.
Cartilage and Skin
- The auricle contains elastic cartilage.
- The dermis is the layer of skin that is beneath the epidermis.
Neuroanatomy
- The gastric glands are effector organs/structures.
- The primary visual cortex is not Brodmann's area of the inferior sagittal sinus.
- Neuromuscular spindles are encapsulated.
- The anterior part of the cerebellum is affected in cerebellar lesions, causing deficits on the same side as the lesion.
Receptors
- Hair follicle receptors are non-capsulated.
- Pacinian corpuscles and Ruffini corpuscles are encapsulated receptors.
