Hippocampus Location Explained
The Hippocampus is a complex brain structure embedded deep into the temporal lobe of the brain.
It plays a major role in the formation of new memories, including spatial and episodic memory, and is also involved in learning and navigation.
Therefore, the Hippocampus is found within The human brain.
Analysis of Options
- The circulatory system: This system deals with blood circulation, not brain structures.
- The human brain: This is the correct location for the Hippocampus.
- Fossils: Fossils are preserved remains of ancient organisms, unrelated to the Hippocampus's location.
- The preschool setting: This refers to an environment for young children, not an anatomical location.
Important Questions from Nervous system
Which one of the following synaptic vesicle proteins is involved in tethering of the vesicle to the cytoskeletal system in the nerve terminus?
In the nervous system, the action potential is generated at the axon hillock in physiological conditions and it is conducted to the terminal end of axon. The location specific origin of action potential and its direction-specific conduction are explained by a researcher in the following proposed statements:
A. The membrane of axon hillock has highest threshold for the generation of action potential
B. The membrane of axon hillock contains large numbers of voltage-gated Na+ channels and that makes it more excitable
C. The propagating action potential in the middle of the axon cannot generate another action potential in the direction of cell body since a large fraction of voltage-gated Na+ channels in the preceding portion is voltage inactivated
D. As the number of voltage-gated Na+ channels is less in the preceding portion of axonal membrane, the propagating action potential in the middle of the axon cannot generate another action potential in the direction of cell body.
Which one of the following combinations represents both correct explanations?
Which one of the following is NOT released by sympathetic preganglionic neurons?
The time taken by synaptic vesicles to travel from the soma of a motor neuron in the spinal cord to its neuromuscular junction in a person’s foot by fast axon transport is about‐
The release of which neurotransmitter from the rods of retina is reduced when light strikes its outer segment?
