What type of myelin is in the peripheral nervous system? What organs are controlled by the somatic nervous system? What is the cell body or soma of a neuron? Define somatic nervous system The somatic nervous system stimulates what muscle?
Q What organs are in the nervous system? A The brain and spinal cord make up your central nervous system. Q How does the nervous system maintain homeostasis? A Homeostasis is the regulation of internal chemistry to maintain a constant internal environment. This state is controlled through various...
Promoting Digestion: When the PNS is activated, it stimulates digestive processes such as increased salivation, improved gastrointestinal motility, and increased blood flow to the digestive organs. These actions help the body process food efficiently, which can be hindered during times of stress. Enhan...
Clusters of cell bodies found in the CNS are callednuclei. This is somewhat confusing, because the term _nucleus_ as applied to individual cells refers to the part of the eukaryotic cell that containsDNA. Clusters of cell bodies found in the PNS, on the other hand, are calledganglia(singula...
Neurons are the excitable cells that carry and process information, whereas the glial cells are the helper cells that protect and support the functions of neurons. The nervous system has two primary components: the central nervous system (CNS) and the peripheral nervous ...
Your body works very similarly. You have sensory organs to send information to the brain—eyes, ears, nose, tongue, and skin. To react, you have muscles that make you walk, talk, focus, wink, stick your tongue out—whatever. Your input/output devices are part of your peripheral nervous ...
the brain, such as locomotion and other reflexes. The nerves of the PNS carry motor commands from the CNS out to muscles, and sensory information from receptor cells to the CNS for interpretation. Besides the movement of skeletal muscles, nerves regulate the activity of internal organs such as...
Efferent neurons are nerve cells that convey chemical and electrical signals from the brain and spinal cord to the organs, muscles...
them with the rest of our body. Very simply, the organs and nerves of the PNS sense and transmit information about conditions inside and outside the body to the CNS where it is evaluated before sending signals back through the PNS to the various parts of the body to regulate their ...
What are the four primary tissue types and their functions? List four organs that make up the urinary system. What is the main function of RBCs? In what ways, are white cells different from red cells by their structure and function?
