The cerebellum of cartilaginous and bony fishes is extraordinarily large and complex. In at least one important respect, it differs in internal structure from the mammalian cerebellum: The fish cerebellum does not contain discrete deep cerebellar nuclei. Instead, the primary targets of Purkinje cells are a distinct type of cell distributed ...
The dentate nucleus is responsible for the planning, initiation and control of voluntary movements. The dorsal region of the dentate nucleus contains output channels involved in motor function, which is the movement of skeletal muscle , while the ventral region contains output channels involved in nonmotor function, such as conscious thought ...
Purkinje cells of the vermis project to the fastigial nucleus, controlling the axial and proximal musculature involved in the execution of limb movements. [10] Purkinje cells in the intermediate zone of the spinocerebellum project to the interposed nuclei, which control the distal musculature components of the descending motor pathways needed ...
The neurons on the parietal associative cortex are most strongly involved in programming and execution of voluntary movements. [8] A learned act is the movement which is produced when the starting sensory signal launches the programmed execution. This action requires the neurons of the parietal associative cortex.
The Purkinje cells that develop later are those of the cerebellum's center-lying section called the vermis. They develop in the cerebellar primordium that covers the fourth ventricle and below a fissure-like region called the isthmus of the developing brain.
The cerebrum is a major part of the brain, controlling emotions, hearing, vision, personality and much more. It controls all precision of voluntary actions, and it functions as the center of sensory perception, memory, thoughts and judgement; the cerebrum also functions as the center of voluntary motor activities.
The cerebellum is the section of the brain that is essential for motor control. As a part of the cerebellum, the flocculus plays a part in the vestibulo-ocular reflex system, a system that controls the movement of the eye in coordination with movements of the head. [1]
The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement. [1] [2] Peripheral structures may include skeletal muscles and neural connections with muscle tissues. [2]
