A 52-year-old woman has difficulty initiating voluntary movements. She can clearly state what she intends to do, describe exactly how she would do it, and picture herself doing it easily. When she is able to begin the motion, she can complete it smoothly and accurately, but she has difficulty beginning the motion. If the difficulty arises from a defect in one particular area of the nervous system, which area is most likely to be involved

Basal Ganglia

Explanation:

The Basal ganglia function is to regulate the voluntary movements or autonomic movement. This is done by receiving and transmission of impulses. Impulses are received for upcoming movement from the cerebral cortex and then process and adjust from where it is convey to the thalamus which then relays this information back to the cortex. The well defined movement instruction is finally sent to the skeletal muscles through the tracts of the pyramidal motor system. It also function in planning and modulation of movement, memory and eye movement.

There are five types of basal ganglia corpus striatum, claustrum, amygdala, substantia nigra and subthalamic sails which all function together.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
