- Only mammals have the outside ear parts called auricles. The ears of different mammals work basically the same way that human ears do. However, many mammals can move their auricles to pick up sound coming from any direction.uricle: bats ear. The huge auricles (outside ear parts) of a bat help it to tell from which direction a sound is coming. Dr. Merlin D. TuttleConservation International/Photo Researchers. The huge auricles (outside ear parts) of a bat help it to tell from which direction a sound is coming.

What is the Utricle? Otolith organs are able to sense gravitational changes and linear acceleration that comes from movement in a straight line. Also called the utriculus, the utricle occupies the bony labyrinth of the inner ear, nestled between the cochlea and the semicircular canals. Otolithic organs detect movement depending on their orientation. Animals or humans without otolithic organs are imbalanced. The utricle detects movement on the horizontal plane of the head, and the saccule detects vertical motion. The utricle is composed of a mass of tiny calcareous stones covered in hair cells embedded in a jelly-like substance containing the calcareous stones.

- In regards the heart, the auricle is a part of the atrium, specifically the small, cone-shaped muscular pouch that projects from it. In the heart, the auricle is a small, cone-shaped pouch that projects from the atrium, one of the upper chambers.The visible part of a person's ear is called the auricle, also known as the pinna.n the context of human anatomy, the auricle can refer to either one of two distinct body parts: the outer ear or an internal “pouch” or protective layer in the heart.

Blocked Eustachian Tubes - Topic Overview The eustachian (say you-STAY-shee-un) tubes connect the middle ears to the back of the throat. The tubes help the ears drain fluid. They also keep air pressure in the ears at the right level. When you swallow or yawn, the tubes open briefly to let air in to make the pressure in the middle ears equal to the pressure outside of the ears. Sometimes fluid or negative pressure gets stuck in the middle ear.

- Updated April 11, 2017. The auditory ossicles are a chain of small bones in the middle ear that transmit sound from the outer ear to the inner ear as a mechanical vibration. The names of these three bones are taken from Latin. The malleus is also known as the hammer, the incus is also called the anvil, and the stapes is known as the stirrup..

Auricle This section is about Structures of the Heart. An auricle is a feature of the anatomy of the heart. There are two auricles in the heart. One auricle is attached to each of the anterior surfaces of the outer-walls of the atria (that is, the left atrium and the right atrium). Visually, they look like wrinkled pouch-like structures. Their purpose is to increase the capacity of the atrium, and so also increase the volume of blood that it is able to contain.

Right Auricle Right Auricle. The right auricle of the heart - also called the right atrial appendage (RAA) - is attached to the heart's right atrium. It's a small, cone-shaped pouch which comes out from the upper and front part of the atrium and overlaps the root of the aorta. The RAA is very muscular, and is lined with small muscles on its surface.

""" Why do I keep having a popping sound in my ear? """ The eustachian tubes are tiny tubes that run between the back of the throat and the middle ear (the part of the ear behind the ear drum). The function of the eustachian tubes is to drain fluid from the middle ear into the throat and also to equalize the pressure behind the ear drum. Sometimes, the eustachian tubes become inflamed and do not function properly. The most common cause of eustachian tube dysfunction is a viral infection like the common cold.

AP Psychology Sensation & Perception ossicles. the middle ear; contains the hammer, anvil, and stirrup which are the smallest three bones the body; when the eardrum quivers it causes the hammer, anvil, and stirrup to hit each other in sequence, then carry the vibrations to the inner ear; stirrup catch the oval window.

What Are the Chordae Tendineae? When the heart beats, the atria (atrial systole) and ventricles (ventricular systole) contract and the open bicuspid and tricuspid valves are pushed closed due to blood pressure in the chambers. The relaxed chordae tendineae tense up to hold the cusps of the atrioventricular valves in place when they close. This prevents prolapsing of the valve leaflets and blood from regurgitating (flowing backwards) into the upper atrial chambers (the left atrium and right atrium).

The Human Heart The two chambers at the bottom of the heart are called ventricles. Their job is to squirt out the blood. In the middle of the heart there is a thick muscle called the septum that separates the left and the right side. The atria and ventricles work together.The atria fill with blood and when they are full they let the blood into the ventricles.When these ventricles pump the blood out of the heart, the atria fill up again and the whole process starts again. There are valves in the heart that make sure that the blood is pumped in the right direction.When the heart contracts, it pumps blood from its chambers into the body.he atria fill with blood and when they are full they let the blood into the ventricles. When these ventricles pump the blood out of the heart, the atria fill up again and the whole process starts again. There are valves in the heart that make sure that the blood is pumped in the right direction.

- 1 The feathers over the ear, called auriculars, are modified to be loose and airy. 2  Owls also have a moveable flap of skin controlled by muscles around the ear opening. 3  This flap protects the ear and concentrates sound waves coming from behind. 4  Many owls also have asymmetrical ear openings.

- The auricle is also known as the pinna, and it is most commonly referred to as the ear. It is the most obviously visible part of the auditory system.An auricle consists of skin over contoured cartilage, and it is held in place by muscles and ligaments.he ear is the first part of the body to come in contact with auditory stimuli. Sound waves must pass over the auricle before entering the ear canal. Then, the waves pass through the tympanic membrane (eardrum) and into the middle ear.

Ears: Facts, Function & Disease Hearing. The external ear, also called the auricle or pinna, is the loop of cartilage and skin that is attached to outside of the head. It works much like a megaphone. Sound is funneled through the external ear and piped into the external auditory canal, according to Nebraska Medicine.

- Left Auricle. The left auricle, also known as the left atrial appendage (LAA), is a flap of heart wall on the anterior surface of the left atrium of the heart. The outermost layer of the auricle is the epicardium, a layer of simple squamous epithelial tissue that gives the auricle a smooth, slick surface. 2  Pericardial fluid is produced by the epicardium to lubricate its surface and prevent irritation during the movement of the heart.
