What is correct in reference with nerve impulse ?
Nerve impulses are self-induced due to the properties of the neuron and its membrane, and they are unidirectional, meaning they travel in one direction from the dendrites to the axon terminal.
The weight of human brain is a and b neuron in it.
The average weight of a human brain is between 1200 to 1400 grams and contains approximately 100 billion neurons. This is a well-established fact in neuroscience.
Which of the following option indicates correct chronology of the meninges from cranium to CNS?
The meninges are the three membranes that cover the brain and spinal cord. From the outside (closest to the cranium) to the inside (closest to the CNS), the correct order is: Dura mater, Arachnoid mater, and Pia mater.
Which of the following option is the correct option for the inner most meninges of CNS?
The innermost layer of the meninges is the Pia mater. It is thin and highly vascularized, meaning it has a rich supply of blood vessels that provide nutrients and oxygen to the brain and spinal cord.
Which of the following is toughest?
The Dura mater is the outermost and toughest layer of the meninges. It is thick, durable, and provides the most significant protection to the brain and spinal cord.
Which of the following does not have lumen?
Which of the following have major coordinating centers for sensory and motor signal?
The thalamus is the major coordinating center for sensory and motor signals. It acts as a relay station, processing and transmitting information from the sensory receptors to the appropriate areas of the brain.
It has centers to regulate body temperature?
The hypothalamus has centers that regulate body temperature. It plays a crucial role in maintaining homeostasis by controlling various autonomic functions, including temperature regulation.
Limbic system along with _____ regulates sexual behavior?
The limbic system, which includes structures such as the hippocampus, amygdala, and parts of the thalamus, is closely associated with the hypothalamus. The hypothalamus plays a crucial role in many autonomic functions of the body, including the regulation of sexual behavior. Therefore, the limbic system in conjunction with the hypothalamus regulates sexual behavior.
Mid brain is located between a and b?
The midbrain, also known as the mesencephalon, is located between the diencephalon (which includes structures such as the thalamus and hypothalamus) and the pons. Understanding the anatomical positioning of the midbrain is crucial for comprehending its role in neural pathways and functions.
