MS1

- A synapse is a junction between two nerve cells (1)

MS2

- Oxygen is used for cell respiration to produce energy (1)

- The brain is highly metabolically active and requires a lot of energy (1)

MS3

- Cerebrum (1)

- Cerebellum (1)

MS4

- Detects changes in body temperature (1)

- Triggers responses to maintain homeostasis (1)

- E.g., sweating to cool down, shivering to warm up (1)

MS5

- Number of synaptic connections increases with age (1)

- Synaptogenesis occurs rapidly during early childhood (1)

- Connections stabilize and some are pruned as the child matures (1)

- Indicates increased neural connectivity and complexity (1)

MS6

- Long dendrites to receive signals from many other neurons (1)

- Long axon to transmit signals quickly over long distances (1)

- Myelin sheath insulates axon, increasing conduction speed (1)

MS7

- Acetylcholine (1)

MS8

- Involved in encoding new memories (1)

- Transfers memories to long-term storage in the cortex (1)

MS9

- Brain weight is generally positively correlated with intelligence (1)

- Larger brains allow for more neurons and connections (1)

- However, encephalization quotient (EQ) is a better measure of intelligence, adjusting for body size (1)

MS10

- Benefits:

- Objective evidence for diagnosis (1)

- May aid in treatment planning (1)

- Risks:

- Accuracy and reliability can vary (1)

- Privacy concerns (1)
