CBNS106 Practicum Flashcards
Medulla
regulates viral autonomic functions like heart rate, blood pressure, and breathing
Pons
relays the information between the cerebrum and cerebellum
- regulates sleep
Midbrain
Regulates alertness and controls reflexes associated with the senses
Superior Colliculus
visual processing and control of eye movements
Inferior colliculus
auditory processing
Hypothalamus
maintains homeostasis and controls endocrine system
Meninges
protect the CNS and contain cerebrospinal fluid
Dura Mater
tough, outermost layer that provides a durable protective shield
Arachnoid Mater
Middle layer that cushions the CNS
Pia Mater
Delicate innermost layer that adheres to the surface of the brain and spinal cord, providing nutrients and support
Cerebrospinal Fluid
cushions the brain and spinal cord and delivers nutrients
Cerebellum
responsible for coordinating voluntary movements
Cerebellar Vermis
coordinating movements related to posture and balance
Cerebellar Hemisphere
fine-tuning motor movements, motor learning and coordination
Frontal Lobe
cognitive functions like problem solving and planning and personality/social behavior
