sensory Flashcards
what is the autonomic nervous system
conveys involuntary and automatic commands that control internal organs and glands
what is the somatic nervous system
conveys information into and out of the central nervous system; voluntary movements of skeletal muscles
what are the three layers of the meninges
dura mater (outer)
arachnoid membrane
pia mater (inner)
what is another name for the forebrain
prosencephalon
what is another name for the midbrain
mesencephalon
what is another name for the hindbrain
rhombencephalon
name the two parts of the rhombencephalon
metencephalon and myelencephalon
name the two parts of the prosencephalon
telencephalon and diencephalon
what is the function of the spinal cord
- Neuronal link between brain and PNS
- intergrating center for spinal reflexes
what is the ventricular system
a network of interconnected, fluid-filled cavities in the brain that produce, circulate, and regulate cerebrospinal fluid (CSF).
what is a doral root
afferent senory
what is a ventral root
efferent motor
what is in the myelencephalon
medulla oblongata (most caudal part of brainstem)
what is the function of the myelencephalon
It contains nuclei that control
vital functions such as control of
breathing and skeletal muscle tone
.
what is in the metencephalon
cerebellum and pons
what is the function of the cerebellum
Receives information from sensory systems, the muscles, and the vestibular system
It co-ordinates this information to produce smooth movements
what is the function of the pons
sleep and arousal
what is in the mesencephalon
red nucleus, periaqueductal grey matter and substantia nigra
what is the function of the red nucleus
coordinates sensorimotor information
what is the function of the substantia nigra
cells make dopamine and project to basal ganglia
what is the function of periaqueductal grey matter
involved in pain suppression due to
naturally high concentrations of endorphins.
what is in the diencephalon
thalamus and hypothalamus
what is the function of the thalamus
Separate but interconnected nuclei receive information from the sensory systems and relay this information to
sensory processing areas in the cortex.
(relay system)
what is the function of the hypothalamus
These control the autonomic nervous system and the endocrine system.
including feeding, sex, sleep,
temperature regulation, and emotional behaviour.
