what is the function of cerebrum cerebellum in the brain? what are cranial, visceral nerves what are resptars and effectors
Answers
Answer:
The cerebellum appears to play several roles. It stores learned sequences of movements, it participates in fine tuning and co-ordination of movements produced elsewhere in the brain, and it integrates all of these things to produce movements so fluid and harmonious that we are not even aware of them...
Explanation:
Functions of the cerebrum: The cerebrum (front of brain) is composed of the right and left hemispheres, which are joined by the corpus callosum. Functions of the cerebrum include: initiation of movement, coordination of movement, temperature, touch, vision, hearing, judgment, reasoning, problem solving, emotions, and learning.
Functions of the cerebellum: The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
Definition of cranial: Your cranial nerves are pairs of nerves that connect your brain to different parts of your head, neck, and trunk. There are 12 of them, each named for their function or structure. Each nerve also has a corresponding Roman numeral between I and XII.
Definition of visceral nerves: Visceral afferent neurons are unipolar neurons that enter the spinal cord through the dorsal root & their cell bodies are located in the dorsal root ganglia. Visceral efferent neurons are motor neurons that conduct impulses to smooth muscle, cardiac muscle, & glands. These neurons make up the Autonomic Nervous System.
What are resptars: Receptors are proteins, usually cell surface receptors, which bind to ligands and cause responses in the immune system, including cytokine receptors, growth factor receptors and Fc receptor. ... Receptors play an important role in signal transduction, immunetherapy and immune responses.
What are effectors: In biochemistry, an effector molecule is usually a small molecule that selectively binds to a protein and regulates its biological activity. In this manner, effector molecules act as ligands that can increase or decrease enzyme activity, gene expression, or cell signaling.
