Block (Trochlea)

Trochlea: anatomical structure that provides trochlear function

The trochlea is an anatomical structure that plays an important role in the functionality of many parts of the body. It can be part of bones, tendons or muscles, and allows you to switch the direction of movement or maintain a certain posture.

One example of a block is the lower epiphysis block at the end of the humerus. This structure allows the bone to move around its axis and perform a wide range of motion. The block in the superodistal corner of the orbit is another example of a block that plays an important role in the function of the eye muscles. This block allows the tendon of the frontal bone and the superior oblique muscle to be tossed over, allowing the eye to move in different directions and maintain its position.

A block can also be described as trochlear, which refers to its ability to block or switch direction of movement. This property makes the block especially important for ensuring the proper functioning of many parts of the body.

It is important to note that malfunctions of the unit can lead to various health problems. For example, damage to the trochlea in the humerus can lead to limited movement in the shoulder and pain, while disruption to the block in the orbit can lead to blurred vision and other eye problems.

In conclusion, the trochlea is an important anatomical structure that provides functionality to many parts of the body. Its ability to block or switch the direction of movement makes it especially important, and disruption of the block can lead to serious health problems.



A block is a part of the anatomical structure of the body that plays an important role in performing a specific function. For example, in biology, a block (tracing paper from the English “trochlea” - gutter, coil) can be found in various organs and systems of humans and animals.

One of the most striking examples of a block is the block of the lower epiphysis of the humerus. This groove-like tube is present at the end of the shoulder and helps strengthen the joint during movement. During intense use, such as heavy lifting, the tendon can injure the surface of the epiphysis, and with a block, injury can be significantly reduced.

The block can also be found in the eyes. The trochlear block is one of the elements of the facial muscles; it is located in the upper distal corner of the eye. The tendons of the frontal lobe and the oblique muscle of the eye are thrown across it, which helps keep the eye from accidentally closing when the head moves. In addition, this block is important for the functioning of the temporomandibular



Block (Trachlea) is a part of any anatomical structure (usually the lower epiphysis of the humerus), thanks to which this structure performs a trochlear function; for example, a block of the lower epiphysis of the humerus and a block of the distal angle of the orbit (angular articulation of the walls of the orbit), through which the block of the superior and inferior oblique muscles of the eye is thrown.
