The Limbic System Most reptiles and lower order organisms only have the “old brain”‚ the evolutionarily oldest part of the brain responsible for vital tasks such as breathing and sleeping‚ whereas higher order organisms have a limbic system. The old brain is comprised of the pons‚ the medulla oblongata‚ the brain stem‚ the thalamus‚ the cerebellum‚ and the reticular formation. The reticular formation is a network inside of the brain stem‚ part of the “old brain” that is essential for arousal (sleeping

Foster Collage of Physical Education & Sports Mr. April 13‚ 2015 What is the Neuromuscular System? According to research the neuromuscular system is to make the body move‚ a signal travels along neurons nerve cells from the brain to the spinal cord. There‚ "lower motor neurons" pass the message on to the muscles. The end of every lower motor neuron releases a chemical‚ which is

cardio-vascular and respiration systems are interrelated‚ and how they function in a specific task/job. Internally in the human body‚ has to be well-controlled and organised with different progressive systems in which they must interconnect and interrelate in order to perform their role efficiently and successfully. There are different types of systems in the body (mainly 10) in which they all function in different ways and interrelate. An example would be the‚ nervous system which in fact regulates all

physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons on why the resting heart rate can fluctuate over time. Factors can include

of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The regulation of breathing is the result of a complex interaction involving a system of sensors‚ a respiratory control center‚ and an effector system to carry out its commands
