Senses in senses: Mechanical senses. ...of this basic design, responsible for detecting the direction of gravity, angular rotation, and sound waves. In the utricle and saccule of the inner ear there are patches of hair cells known as maculae. Within each maculae, the stereocilia are embedded in a gelatinous mass known as the otolithic membrane, which contains small stonelike calcium carbonate particles called otoconia.

What do the inner ear contains? The vestibule is the region of the inner ear where the semicircular canals converge, close to the cochlea (the hearing organ). The vestibular system works with the visual system to keep objects in focus when the head is moving. Joint and muscle receptors also are important in maintaining balance.

The Inner Ear The auditory nerve carries impulses from the cochlea to a relay station in the mid-brain, the cochlear nucleus. These nerve impulses are then carried on to other brain pathways that end in the auditory cortex (hearing part) of the brain.Also housed within the inner ear are the semicircular canals, the utricle, and the saccule. These structures help control one’s sense of steadiness or balance.he inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph).

- In terms of structure, more information regarding the saccule has been provided. The saccule lies in an approximately para-sagittal plane on the medial wall of the vestibule. The saccular macula is elongated through the anterior-posterior dimension. The neuroepithelium is densely populated with receptor hair

Macula of retina The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disk is located towards the nose. The macula or macula lutea (from Latin macula, spot + lutea, yellow) is an oval-shaped pigmented area near the center of the retina of the human eye and some other animalian eyes.

Fovea centralis The most sensitive region of the macula is the fovea (it has an even higher density of cones). The rest of the retina's surface handles our peripheral vision, and this is where most of the rod photoreceptors of the retina are located.

Human Physiology/Print Version The Organ of the Corti is responsible for hearing, and it's found in the inner ear. The Organ of the Corti has hair cells on it that vibrated in response to Amy hearing someone asking for a piece of gum. The hair cells then transmit the stimuli to the brain for interpretation of the sounds.

Macular Degeneration Home » Resources » Diseases & Disorders » Retinal Disorders » Macular Degeneration. The macula is the most central portion of the retina, directly opposite the lens. It is where the greatest number of light sensitive cells, called cones, are located. Cones allow us to see color and fine detail. The high concentration of cones in the macula gives people extremely detailed and rich central vision.

Ch. 13 Anatomy & Physiology of the Ear The labyrinth consists of the cochlea, vestibule, and three semicircular canals. Hair cells called the organs of Cort line the inner ear. These hair cells change the sound vibrations to electrical impulses and send the impulses to the brain via the vestibulocochlear nerve.

- Macula densa cells in the distal nephron, according to the classic paradigm, are salt sensors that generate paracrine chemical signals in the juxtaglomerular apparatus to control vital kidney functions, including renal blood flow, glomerular filtration, and renin release.

The Vestibulocochlear Nerve (CN VIII) The cell bodies of the vestibular nerve are located in the vestibular ganglion which is housed in the outer part of the internal acoustic meatus. Information about the position of the head is used to coordinate balance and the vestibulo-ocular reflex.

BIO 210 (LAB Practicum #4) Eye, Ear and Organ of Corti Where in the cochlea are the hairs associated with hearing? hair cells are located within the organ of Corti on a thin basilar membrane in the cochlea of the inner ear. They derive their name from the tufts of stereocilia that protrude … from the apical surface of the cell, a structure known as the hair bundle, into the scala media, a fluid-filled tube within the cochlea.

Macula of saccule The vestibule is a region of the inner ear which contains the saccule and the utricle, each of which contain a macula to detect linear acceleration. The macula of saccule lies in a nearly vertical position. Its function is to detect vertical linear acceleration. It is a 2 mm by 3mm patch of hair cells.

The Screen of the Eye: Retina The area of the retina responsible for more detailed vision is called the Macula. The optic nerve is responsible for carrying signals from the retina to the brain through the optic disc. The fovea at the center of the macula packed with millions of light sensitive cells is the most sensitive part of the retina.

Epiretinal membrane At the very centre of the retina is the macula. This is a very special area of the retina, which we use for reading and recognising complex shapes. Sometimes, scar tissue forms which grows across the macula. As the membrane contracts, it causes distortion of the retinal tissue.

Renal Physiology The macula densa cells are specialized cells located in the distal tubule that detect the sodium concentraiton in the filtrate. A high concentrtion of sodium in the filtrate indicates that there has been an increase in GFR and therefore more filtration in the glomerulus.

Utricle (ear) The utricle, along with the saccule, is one of the two otolith organs located in the vertebrate inner ear. The utricle and the saccule are parts of the balancing apparatus (membranous labyrinth) located within the vestibule of the bony labyrinth (small oval chamber). These use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation.

Macula densa In the kidney, the macula densa is an area of closely packed specialized cells lining the wall of the cortical thick ascending limb, at the transition to the distal convoluted tubule. The cells of the macula densa are sensitive to the concentration of sodium chloride in the late thick ascending limb.his demonstrates the macula densa feedback, where compensatory mechanisms act in order to return GFR to normal. The release of renin is an essential component of the renin–angiotensin–aldosterone system (RAAS), which regulates blood pressure and volume.

Anatomy of a Normal Human Eye An area of the eye near the center of the retina where visual perception is most acute. The macula is responsible for the sharp, straight-ahead vision that is used for seeing fine detail, reading, driving, and recognizing faces. It is one hundred times more sensitive to detail than the peripheral retina.

The Inner Ear The Inner Ear. Parts of the Ear: Outer Ear | Middle Ear | Inner Ear. The inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph). The Organ of Corti is the sensory receptor inside the cochlea which holds the hair cells, the nerve receptors for hearing.

What is a macular hole? A macular hole is a small break in the macula. The macula is located in the center of the retina, an area of light-sensitive cells at the back of the eye. The macula controls central vision, which is the sharp, straight-ahead vision we need for reading, driving, and seeing fine detail. A macular hole can cause blurred and distorted central vision.
