Which section of the brain is responsible for coordinating muscle movements
jarptica [38.1K]

Answer:

The cerebellum (back of the brain) and the brainstem (middle of the brain)

Muscle movement coordination can be<em> voluntary</em> or <em>involuntary</em>. There are different sections of the brain responsible for the two;

  • Voluntary movement of muscles is coordinated by the brainstem in addition to other functions such as sneezing, swallowing, vomitting, etc.
  • Involuntary coordination of muscles is controlled by the cerebellum in addition to maintaining posture, balance and body equilibrium.

Hence, both the cerebellum and the brainstem are responsible for coordinating muscle movement.

Emily is a 25-year-old asian female. emily is complaining of frequent headaches over the past 3 weeks. emily is taking birth con
Tomtit [17]
Emily's symptoms include frequent headaches, light sensitivity, nausea and vomiting. The risk factors are her smoking habit and the birth control pills that she is currently taking. A possible diagnosis could be an acute condition which is caused by a serious interaction between her smoking activity and her birth control pills. It has been proven that women who smoke while on contraceptive therapy have an increased risk of heart attack and stroke. This is because nicotine increases heart rate and blood pressure, while certain hormones present in some birth control pills (such as estrogen) increase the tension on blood vessels. For further diagnosis, the healthcare professional should check Emily's blood pressure and ask her family history on blood clots, heart problems, or stroke cases.
