Question

After suffering a bad fall while rock climbing, charisa experienced profound alterations in her ability to plan and produce movement. Which brain structure did charisa's injuries most likely affect?

Answer 1

Charisa's ability to plan and produce movement could be compromised due to damage to her cerebellum and possibly the basal ganglia, which are involved in movement control, coordination, and posture as part of the motor division of the central nervous system.

Step-by-step explanation:

Charisa's injuries from a bad fall while rock climbing likely affected her cerebellum and possibly other parts of her brain involved in movement coordination, such as the basal ganglia. The cerebellum is responsible for fine-tuning movements, balance, coordination, and posture. When the cerebellum is damaged, an individual might display a broad range of motor control issues like difficulties in walking, maintaining balance, or planning and producing movement.

The basal ganglia are a group of interconnected brain areas that coordinate messages between various other brain areas. Damage to the basal ganglia, often seen in conditions like Parkinson's disease, can result in motor impairments and affect voluntary movements, posture, and balance.

Both the cerebellum and the spinal cord, which might also be affected given its role in relaying motor commands from the brain to the body, belong to the motor division of the central nervous system. This division is involved in processing and executing movement-related information.

Answer 2

The answer is "substantial nigra".

The substantia nigra is a nucleus in the midbrain that is considered piece of the basal ganglia.Most of the dopamine neurons of the cerebrum start in the midbrain and are found in either the substantia nigra or the ventral tegmental zone, which is found contiguous the substantia nigra.

Being one of the significant dopamine-delivering regions of the brain, however, the substantia nigra has capacities that stretch out past simply engine control. It is likewise thought to assume vital jobs in various different capacities and practices, including learning, medicate enslavement, and feeling.
