Fetal Development
This stage if from conception to 2 weeks.
What is the: pre-embryonic stage
The only organ with direct connection with the SNS
What is the Adrenal medulla
Sensory receptors use these pathway types
What are afferent pathways
This is the primary relay center of the brain. and is made up of this matter type.
What is the thalamus, grey matter
This part of the brains primary action is to coordinate movement
what is the cerebellum
This develops into the dermis, muscles, skeleton, excretory and circulatory system
what is the: Mesoderm
These neurons consist of multiple dendrites connected to the soma and a single axon
what are multipolar neurons
These are the 4 main types of receptors
what are: chemo, thermo, mechano, nocioceptors
These are the two components of the cerebrum
This lobe integrates sensory emotional and cognitive information fro self-awareness and regulation
what is the insular lobe
This will develop to form the CNS
What is the: Neural tube
Least common neuron type. It is highly specialized and act as sensory neurons restricted to specific sensory systems.
what are Bipolar neurons
These pre-ganglionic cell bodies of the PNS are located in which regions of the spinal cord specifically
What is the brainstem and sacral region at s2-s4.
These are the components of the brainstem from rostral to caudal
what is: midbrain (mesencephalon), pons, medulla oblongata
The midbrain is associated with these CN
what are CN 3&4
This arises from the mesoderm and development first begins to form by day 18
What are somite
More common in the PNS they typically carry sensory info from the peripheral tissue of the body up towards the spinal cord and CNS via their central axon.
What are psuedo-unipolar neurons
In the indirect sympathetic pathway, this is the neurostransmitter and receptor type located at the first synapse
The pons is associated with this cranial nerve
what is CN 5
This carries neural signals between the cerebral cortex and the and deeper subcortical structures. And is categorized by this matter type.
what is the internal capsule, white matter
Around days 22–24, a somite begins to differentiate into these three specialized structural zones.
What are: myotome, dermatome, sclerotome
These largely operate as motor neurons throughout the body with some directly innervating muscle tissue
what are multipolar neurons
In the direct adrenal medulla sympathetic pathway these hormones are released into the bloodstream and bind to these receptor types at the target organ
what is- epinephrine/NE and adrenergic receptors
The veins within the skull that drain into the IJV
what are dural sinusus
The arteries of the brain deliver about this amount of cardiac output and consume this amount of the bodys resting oxygen
what is 1/6 and 1/5
