Question

как строение зрительной сенсорной системы связано с функциями на примере строения продолговатого мозга???????

Answer 1

Ответ:

Строение головного мозга человека. Посмотрите видео-объяснение темы. Преподаватель Фоксфорда всё подробно расскажет и покажет. ... В отличие от спинного мозга он не имеет метамерного, повторяемого строения, серое вещество в нем расположено не в центре, а в периферических ядрах. В продолговатом мозге находятся перекресты нисходящих и восходящих путей, ретикулярная формация. Ретикулярная формация. ... Мозжечок лежит на задней поверхности моста и продолговатого мозга в задней черепной ямке. Состоит из двух полушарий и червя, который соединяет полушария между собой. Белое вещество мозжечка покрыто корой из серого вещества.

Answer 2

Structure of the Visual Sensory System

The visual sensory system is responsible for processing visual information and transmitting it to the brain for interpretation. The structure of the visual sensory system is closely related to its functions, and one example of this relationship can be seen in the structure of the medulla oblongata, also known as the brainstem.

The medulla oblongata is located at the base of the brain and is involved in various vital functions, including the regulation of breathing, heart rate, and blood pressure. It also plays a crucial role in the visual sensory system.

The medulla oblongata contains several important structures that are involved in visual processing, including the optic tracts, the superior colliculus, and the inferior colliculus. These structures work together to transmit visual information from the eyes to the brain and coordinate visual reflexes.

Optic Tracts

The optic tracts are a pair of nerve pathways that carry visual information from the eyes to the brain. They originate at the optic chiasm, where the optic nerves from each eye cross over. The optic tracts then continue to the lateral geniculate nucleus (LGN) in the thalamus, which acts as a relay station for visual information before it is sent to the visual cortex in the occipital lobe of the brain.

Superior Colliculus

The superior colliculus is a structure located in the midbrain that plays a crucial role in visual processing. It receives visual information from the optic tracts and is involved in the coordination of eye movements and visual attention. The superior colliculus helps to direct the eyes towards objects of interest and plays a role in the generation of saccadic eye movements.

Inferior Colliculus

The inferior colliculus is another structure located in the midbrain, but it is primarily involved in auditory processing. However, it also receives visual input from the superior colliculus and is involved in multisensory integration. The inferior colliculus helps to integrate visual and auditory information and coordinate responses to sensory stimuli.

Function-Structure Relationship

The structure of the medulla oblongata, particularly the optic tracts, superior colliculus, and inferior colliculus, is closely related to the functions of the visual sensory system. These structures work together to transmit visual information, coordinate eye movements, and integrate visual and auditory stimuli.

In summary, the structure of the medulla oblongata, including the optic tracts, superior colliculus, and inferior colliculus, is closely related to the functions of the visual sensory system. These structures play a crucial role in transmitting visual information, coordinating eye movements, and integrating visual and auditory stimuli
