3 - Reflexes Flashcards
What are mammals and why is this important? (Reflexes Developmental)
- Endothermic (warm blooded)
- Can maintain body temperature at a constant is food intake is adequate
Primate infants are known as what and give an example? (Reflexes Developmental)
- Preconscious (highly advanced)
- Ears and eyes are open upon birth
What are mammals known as when they have an extended juvenile life period? (Reflexes Developmental)
Altricial
What stage of development is specific to only humans? (Reflexes Developmental)
Post-reproductive stage (menopause)
Define vestigial? (Reflexes Developmental)
Partly or wholly lost original function
Give an example of a vestigial reflex in the primate order? (Reflexes Developmental)
Monkeys clinging to a mothers fur
Give examples of a neonatal reflex? (Reflexes Developmental)
- Moro reflex
- Step reflex
- Grasp reflex
What is the Brazelton’s assessment? (Reflexes Developmental)
Tests newborns reflex ability
What is the importance of glia in post natal brain growth? (Reflexes Developmental)
Provide structural support, maintenance and insulate neuronal axons with myelin
What is myelination? (Reflexes Developmental)
Formation of fatty sheaths around axons
What is the importance of axons? (Reflexes Developmental)
Accelerate neurotransmission
At what speed does an un-myelinated sheath transmit? (Reflexes Developmental)
1 m/s
At what speed does a myelinated sheath transmit? (Reflexes Developmental)
10-100 m/s
What is synaptogenesis? (Reflexes Developmental)
The formation of new connections between neurons
What changes in synaptogenesis? (Reflexes Developmental)
The activity between cell bodies, not the number of cell bodies
