Leg (Crus)

A crus is an elongated structure that may be part of a structure. In some cases, the stalk may be one component of a structure that has a more complex shape. For example, the cerebral peduncle (cerebrum) is a paired white cord that emerges from the cerebral pons and goes forward to the cerebral hemispheres.

The cerebral peduncle consists of many components, including nerve fibers, nerve substance, reticular formation, and a number of nuclei. It plays an important role in coordinating movements and regulating muscle tone. In addition, the leg is involved in the processes of perception and processing of information, as well as in the regulation of emotional state.

However, it should be noted that the peduncle is not the only component of the brain. The brain is made up of many other structures such as the cerebral cortex, basal ganglia, cerebellum, and others. Each of these components performs its own functions and interacts with other brain structures.

A pedicle is an elongated structure that may be part of the structure of the body. In medicine, especially in anatomy and physiology, the term “peduncle” is often used to refer to various structures, such as the cerebral peduncle, which is one of the important elements of the central nervous system.

The cerebral peduncle is a paired formation located on the posterior surface of the brain. It is formed by a white round cord that emerges from the pons and moves forward to the cerebral hemispheres. This structure consists of nerve fibers, nerve cells, reticular substance and a number of nuclei, including the red nucleus.

The functions of the cerebral peduncle include controlling movement, regulating muscle tone, and maintaining balance. In addition, it is involved in processing information from the senses and regulates many body functions such as breathing, heart rate and blood pressure.

Thus, the crus is an important part of the central nervous system and plays an important role in maintaining the health and functioning of the body.

What is a crus? **Stem** - an elongated formation that is part of some structure; lengthening something. In anatomy, the **leg** (English Crus, literally - split, split, lobed; Latin crus - leg, knee) is considered as the anterior part of the cerebral hemisphere, located between the large vertical surface of the hemisphere and the substance of the diencephalon (pons), ending depressions and grooves leading to the sphenoid. **Transverse peduncles** are areas of the cerebral hemispheres from which connective fibers go to the inferior colliculus and the corpus callosum. Their length and proximity to the brain mass play an important role in normal brain maturation in mammals and humans. For example, ethanol, which causes a decrease in the number of cholinergic neurons in the midbrain, suppresses the growth of the transverse peduncles in the hippocampus of rats, and stimulation with cholinergic normalizes their size. The term "transverse peduncle" should be used only in reference to the surfaces of the forebrain hemispheres and not in reference to the hollow optic disc itself, and the term "large transcortical peduncle" parallel to the pons should be avoided. In embryology, **pedicles of the sphenoid bone** are called growth cartilaginous brushes that serve to fix the sphenoid sinus during its growth. During intrauterine development, the cartilaginous tissue of the brushes is replaced by bone, as a result of which they do not ossify, being located on the wedge-shaped processes.

The cerebral peduncle: anatomy, physiology, functions The cerebral peduncle is its unpaired convex section, which lies between the pons and the occipital lobes of the cerebral hemispheres. Unlike other brain structures, the peduncle is well formed at any age.
