Frontal lobes
Frontal Lobes
The Frontal Lobes (pronunciation: /ˈfrʌntəl loʊbz/) are the largest of the four major lobes of the brain in mammals, and are located at the front of each cerebral hemisphere. They are separated from the parietal lobes by the central sulcus, and from the temporal lobes by the lateral sulcus.
Etymology
The term "Frontal Lobe" is derived from the Latin word "frontalis", meaning "of the forehead", and the Greek word "lobos", meaning "a small rounded projection or division". This is due to the location of the frontal lobes at the front of the brain, underneath the forehead.
Function
The frontal lobes are involved in a variety of functions, including:
- Motor Function: The frontal lobes contain the primary motor cortex which controls voluntary movements.
- Problem-Solving: The frontal lobes are essential for tasks which require planning and decision making.
- Memory: The frontal lobes are involved in the retrieval and maintenance of long-term memories.
- Language: The frontal lobes, specifically Broca's area, are involved in speech production.
