The eye contains sensory receptors for vision. Light enters through the cornea and lens, and forms an image on the retina. Rods and cones on the retina detect light and send signals through the optic nerve to the brain. The ear contains sensory receptors for hearing and balance. Sound waves enter through the outer ear and cause the eardrum and middle ear bones to vibrate, transmitting vibrations through the oval window to the cochlea of the inner ear. Hair cells in the cochlea detect these vibrations and send signals through the vestibulocochlear nerve to the brain.

Maintaining eye and ear health through regular checkups is important for these vital senses.
Hearing
The document describes the anatomy and physiology of the human ear and vestibular system. It explains that sound waves are channeled through the outer ear to the tympanic membrane, causing the ossicles to vibrate and transmit the vibrations through the oval window to the cochlea. Within the cochlea, vibrations stimulate hair cells which transduce the mechanical signal into neural impulses that travel to the brain. The vestibular system contains semicircular canals and otolith organs that provide the senses of balance and spatial orientation through the detection of head motion.
Ear parts and its function
The document discusses the three main parts of the human ear - the outer, middle, and inner ear. The outer ear collects sound waves and directs them through the ear canal to the eardrum. The vibrating eardrum then sends these sound waves through a series of three small bones in the middle ear. These vibrations cause fluid in the coiled inner ear to move, stimulating nerve cells that send sound messages to the brain.
Cerebrum
The cerebrum is the largest part of the human brain and consists of two hemispheres separated by the longitudinal cerebral fissure. Each hemisphere has an outer layer of grey matter called the cerebral cortex and an inner mass of white matter. The cortex is highly folded to fit within the skull, forming convolutions called gyri separated by sulci. The cortex can be divided into four lobes - frontal, parietal, temporal and occipital - based on sulci and gyri. Within each lobe are functional areas including motor, sensory, and association areas that control voluntary movement, process sensation, and integrate sensory information respectively.
Anatomy and physiology of the Inner ear, and Motion Sickness
This presentation discusses the motor functions of the brain stem and cerebral cortex. It begins with an introduction to the brain stem, which plays a major role in controlling eye movement and supporting the body against gravity. It then discusses the reticular formation in more detail, including its sensory and motor neurons. The presentation goes on to describe the vestibular apparatus, including the utricle, saccule, and semicircular canals. It explains their roles in balance and sensory transduction. Finally, it briefly discusses motion sickness, its causes when vision and balance senses disagree, and some advice to prevent it like looking out windows or taking scopolamine.
Brain of scoliodon

The cerebellum covers the diencephalon in the midbrain. The hindbrain consists of a highly developed cerebellum and medulla oblongata, which controls involuntary activities. There are eight cavities or ventricles in the brain that are connected, including the rhinocoel, paracoels, diocoel, optocoel, epicoel, and metacoel.
ppt of Sensory organ
The ear is divided into three parts: the outer, middle, and inner ear. The outer ear collects sound waves and directs them through the external auditory canal to the eardrum. The middle ear contains three small bones (ossicles) that amplify vibrations through bone conduction to the inner ear. The inner ear converts vibrations into neural signals for hearing and balance via the cochlea and semicircular canals. Sound waves are transduced into mechanical, then hydraulic, then electrical energy as they travel through the ear to be interpreted by the brain.
Gyri and Sulci of cerebrum
The document describes the lobes, sulci, and gyri of the cerebral hemispheres. It notes that the cortex is folded into gyri separated by sulci, greatly increasing the surface area. The four main lobes are frontal, parietal, temporal, and occipital. Key sulci include the central sulcus, lateral sulcus, calcarine sulcus, cingulate sulcus, and intraparietal sulcus. The frontal lobe contains the precentral and inferior frontal gyri. The parietal lobe contains the postcentral and superior/inferior parietal gyri. The temporal lobe contains the transverse temporal gyri including Heschl's gyrus. The occipital lobe contains
Inner ear embryology and anatomy
The inner ear begins developing between 3-16 weeks of gestation, forming otic discs, pits, and cysts from ectoderm thickening over the hindbrain. Each otocyst divides into ventral and dorsal parts, forming the saccule, cochlear duct, utricle, semicircular canals, and endolymphatic duct. The cochlear duct coils from base to apex, reaching 2.5 coils by 25 weeks. Sensory cells in the maculae, cristae, and organ of Corti develop between 11-16 weeks.
The special senses
This PowerPoint presentations covers the anatomy and physiology of the eyes, ears, nose and mouth; and common disorders.
The human ear
The human ear has three parts - the outer, middle, and inner ear. Sound travels through the outer ear and vibrates the eardrum, causing the middle ear bones to vibrate as well. This movement is transferred to the inner ear, where fluid causes hair cells to bend and send signals through the auditory nerve to the brain for interpretation as sound.
Cranial nerves

Internal ear 1 by P.R.Desai Prof & HOD Physiology, DYPMCKOP
The internal ear contains the cochlea for hearing and the vestibular apparatus for balance and posture. The cochlea contains three fluid-filled spaces that spiral around a central pillar. Hair cells located on the basilar membrane detect sound vibrations. The organ of Corti contains inner and outer hair cells that project stereocilia into the tectorial membrane. Vibrations cause the stereocilia to bend, triggering nerve impulses. The basilar membrane contains fibers of varying lengths that vibrate at different frequencies, allowing for sound detection and discrimination. The hair cells play key roles in hearing by generating action potentials and controlling sensitivity.

It describes the anatomy and physiology of the eye, ear, olfactory epithelium, and taste buds. Light is detected by rods and cones in the retina and sound waves are detected by hair cells in the cochlea. Odorants activate olfactory cells and different chemicals stimulate gustatory cells to detect the basic tastes.
Senses ppy
The document summarizes the structure and function of the human ear, eye, and associated sensory systems. It describes the three main parts of the ear - outer, middle, and inner ear. Sound waves are collected by the outer ear and transmitted through the middle ear via the auditory ossicles to the inner ear, where they are converted to nerve impulses. The inner ear also contains structures for balance. Similarly, it outlines the three layers of the eye - outer fibrous layer, middle vascular layer, and inner nervous layer. Light enters through the cornea and lens, stimulating photoreceptors in the retina which transmit signals to the brain via the optic nerve. Both sensory systems provide vital functions of hearing, balance,
Eye + ear
The document provides an overview of the anatomy of the eye and ear. It describes the structures of the orbit, including the bones that make up its walls. It details the layers of the eyeball - fibrous, vascular and sensory layers - and identifies structures within each layer. These include the sclera, cornea, iris, choroid, ciliary body and retina. It also outlines the chambers of the eye and the extraocular muscles. For the ear, it identifies the external, middle and inner ear structures, such as the auricle, tympanic membrane, auditory ossicles, cochlea and vestibular system. It provides a brief overview of the nerves, blood supply and functions associated with

The inner ear, where the semicircular canals are located that help with balance and equilibrium. Excessive stimulation of these centers in the inner ear can lead to motion sickness.
Special senses
The document summarizes the key aspects of the special senses - vision, hearing, equilibrium, smell, and taste. It describes the anatomy and physiology of the eyes, ears, nose, and tongue. For vision, it outlines the structures of the eye like the retina, cornea, lens, as well as how light is focused and transmitted as nerve impulses. For hearing and equilibrium, it discusses the outer, middle and inner ear structures, how sound is transmitted through the ossicles and processed in the cochlea and vestibule. It also explains smell and the olfactory receptors and pathways. Finally, it covers taste buds and the four basic taste sensations.
A&P Chapter 24 Special Senses
This chapter discusses the special senses of vision, hearing, smell, taste, and touch. It provides an overview of the anatomy and functions of the eye, ear, and sensory receptors for smell and taste. Common disorders are also mentioned for the eye and ear. The case study asks about why children get ear infections more than adults and the relationship between ear pain and appetite. Tylenol may be prescribed as it can help reduce fever and pain associated with ear infections.
A&P Lab 2 midterm review
The document provides information about the structure and function of the peripheral and central nervous systems, including:
- The divisions of the peripheral nervous system include the afferent sensory division and efferent motor division. The efferent system has somatic and autonomic divisions.
- Neuron structure includes the dendrites, cell body, axon, axon collaterals, nodes of Ranvier, and synaptic end knobs. Myelin sheaths insulate some axons.
- Neuroglial cells include Schwann cells, oligodendrocytes, astrocytes, microglia, and ependymal cells.
- The meninges are membranes that surround and protect the central nervous system.
