Summary
The triticeal cartilage (TC) was found in 33% of cadavers. Its presence is linked to shorter superior horns of the thyroid cartilage (SHTC) only when the TC is present or absent bilaterally.
Area of Science:
- Anatomy
- Morphology
Background:
- The triticeal cartilage (TC) is a variable anatomical structure within the thyrohyoid membrane.
- Its absence is hypothesized to correlate with a longer superior horn of the thyroid cartilage (SHTC).
Purpose of the Study:
- To determine the prevalence of the triticeal cartilage (TC).
- To investigate the relationship between SHTC length and TC presence.
Main Methods:
- Dissection of 87 adult cadavers.
- Collection of data on TC presence/absence and SHTC length.
Main Results:
- A TC was identified in 33% of cadavers.
- No significant difference in SHTC length was observed in cases of unilateral TC.
- Significantly longer SHTCs were found in cadavers lacking bilateral TCs compared to those with bilateral TCs.
Conclusions:
- The triticeal cartilage (TC) has a prevalence of 33%.
- A relationship exists between TC presence and SHTC length, specifically in individuals with bilateral TC or complete absence of TC.

01:21Larynx
5.5K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

5.6K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

01:17Structural Joints: Cartilaginous Joints
4.5K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

01:20The Thoracic Cage: Ribs
10.0K
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal...

01:17The Thoracic Cage: Sternum
9.3K
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid...

01:11The Auditory Ossicles
3.5K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
