It also controls how your body reacts when there is an emergency. As I mentioned earlier the nervous system is a very complicated subject to talk about as it is comprised of different levels of organization.
The diencephalon, alongside the cerebrum make up the two major divisions of the forebrain. The main structures of the diencephalon include the hypothalamus, thalamus, epithalamus (including the pineal gland), and also the subthalamus. Moreover, located within the diencephalon is found the third ventricle, which is one of the four brain ventricles or cavities filled with cerebrospinal fluid. The function of the diencephalon is to relay sensory information between brain regions and control many autonomic functions of the peripheral nervous system.
The nervous system is the body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) are made of nerves. The brain is made of three main parts which are the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus. The midbrain consists of the tectum and tegmentum.
The input nuclei receives signals and the output signal sends the signals to the part of the brain that processses the signals. They are responsible for voluntary movement and cognitive functions. In addition, the basal ganglia are associated with processing emotions. The basal ganglia ensure that involuntary movements are avoided and enable voluntary movements. Through these, the motor cortex is able process information concerned with
The blood carries oxygen from the lungs of the respiratory system to the body’s cells, and take carbon dioxide from the cells to the lungs. The tissues from the circulatory system makes up the heart and blood vessels, which are part of the muscular system. Finally, the nervous system sends signals from the brain to the heart for it to pump blood throughout the body. By studying the circulatory system, and following the rules of the levels of organization, we know that the system is made up of organs, such as the heart and blood vessels. The organs are made up of tissues working together, such as the smooth/cardiac muscle tissues and blood.
There are actually two types of our nervous system. These are the peripheral nervous system and the central nervous system, but we will talk about
The human body consists of eleven major organ systems that maintain homeostasis: the skeletal, muscular, circulatory, nervous, respiratory, digestive, urinary, endocrine, reproductive, integumentary and lymphatic systems. These organ systems are dependent on each other to keep the human body in homeostasis. For example, the nervous and endocrine systems coordinate functions of other body systems because they allow information to be communicated throughout the body. The nervous system consists of the brain, nerves, and spinal cord. It is the fast acting control system because it responds to internal and external changes throughout the body.
2. Describe how the body systems affect one another. How body systems affect each other is for example when the circulatory system works with the respiratory system. They work together because when you breathe in you take in oxygen and the respiratory system does its job and then the circulatory system takes the oxygen and sends it to your other parts. 3.
There are various types of neurotransmitters and they are located throughout your entire body. The diverse group of neurotransmitters contribute to many functions such as muscle activity, activity in the brain, and the nervous system. (p. 93) 2. Are people more or less likely to catch deception if they are aware that it may occur? People who are aware of the possibility that something may occur, are more likely to spot a trick compared to those who are not prepared.
It also has a very thick cardiac muscle wall (myocardium), this is because it needs a strong wall to be able to push the oxygenated blood to all areas of the body. The heart also contains (i) The tricuspid and bicuspid valves- these are situated between the atrium and ventricle. It is there to prevent backflow of blood from the ventricle to the atrium, it is a one way flow of blood.
The PNS contains somatic nervous system and the autonomic nervous system. The autonomic nervous system controls the function of internal organs like your heart, stomach, cardiac muscle, and your glands. The autonomic nervous system has an effect on the organs, muscles, and glands are all done voluntary. The autonomic nervous system can change the body temperture, send extra blood to a particular area, slow your heartbeat, and pull the stomach secretion. The somatic nervous system is made up of sensory organs and nerves that connects to the skin, also that connects to all the skeleton muscles.
The brain is the most complex organ in our body. It serves as the command center of the human nervous system. The brain is composed of different parts and functions that are dependent upon each other. The brain consists of two distinct sides: the right and left cerebral hemispheres. The side of the brain that endures damage will impact the function on the opposite side of the body and impairs mental capabilities.
