What type of tissue is in the ear?
Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts, such as ears, nose, and epiglottis (Hutmacher et al., 2003).
What are the 3 layers of the ear?
The three sections are known as; the inner ear, the middle ear, the outer ear. The inner ear is made up of the cochlea, the auditory nerve and the brain. The middle ear consists of the middle ear bones called the ossicles (malleus, incus, stapes).
What connective tissues make up your ear?
Auricular cartilage is flexible, connective tissue, sometimes referred to as gristle. This type of cartilage is known as elastic cartilage. It contains no nerve cells or blood vessels, and is semi-opaque (somewhat see-through).
What are the cells in your ear called?
It consists of tiny hair cells that line the cochlea. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves. In this cut-view, you can see the organ of Corti with its four rows of hair cells.
What tissue is found in the outer ear?
The external auditory canal also has keratinized stratified squamous epithelium that covers the external tympanic membrane as well. Cerumen is wax produced by the sebaceous glands. The inner ear has a columnar epithelium overlying vascular stroma in the vestibular labyrinth.
What is called tympanum?
Overview. The tympanic membrane is also called the eardrum. It separates the outer ear from the middle ear. When sound waves reach the tympanic membrane they cause it to vibrate.
Where are the ears located on a human?
The ear is the organ that enables hearing and, in mammals, balance. In mammals, the ear is usually described as having three parts—the outer ear, the middle ear and the inner ear. The outer ear consists of the pinna and the ear canal….

What is smallest bone in human body?
At 3 mm x 2.5 mm, the “stapes” in the middle ear is the smallest named bone in the human body. The shape of a stirrup, this bone is one of three in the middle ear, collectively known as the ossicles.
What is connective tissue example?
Specialized connective tissues include a number of different tissues with specialized cells and unique ground substances. Some of these tissues are solid and strong, while others are fluid and flexible. Examples include adipose, cartilage, bone, blood, and lymph.
Which fluid is present in ear?
Within the inner ear, there are two types of fluid — endolymph (inner fluid), and perilymph (outer fluid), separated by a membrane.
What is the external ear called?
Pinna
External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear. External auditory canal or tube.
How are the three parts of the ear related?
All three parts of the ear are important for detecting sound by working together to move sound from the outer part through the middle and into the inner part of the ear. Ears also help to maintain balance. The outer part of the ear collects sound. Sound travels through the auricle and the auditory canal, a short tube that ends at the eardrum.
What happens when tissue builds up in the inner ear?
If the buildup of tissue spreads to the inner ear, it is called Cochlear Otosclerosis. This can cause permanent sensorineural hearing impairment due to interference with how the nerves in this part of the ear work.
How is the simple epithelium different from other tissues?
Simple epithelium is composed of a single layer of cells and functions as a lining for body cavities, ducts, and tubes similar to skins; the compound epithelium consists of two or more cell layers and has protective function. Figure 13.10. Shows simple epithelium is further divided into three types. (iv) Columnar cells bearing cilia.
How are the different types of cells in the body different?
Cells comprise tissues, tissues make up organs, organs form organ systems, and organ systems work together to create an organism and keep it alive. Each type of cell in the human body is specially equipped for its role. Cells of the digestive system, for instance, are vastly different in structure and function from cells of the skeletal system.
