Fichas del conjunto (26)
- 1What does the CNS do?Mediates sensory input and motor output.
- 2What is in the PNS and what does it do?Spinal nerves and cranial nerves.
Autonomic nervous system.
Carries information into and out of CNS. - 3What does the sympathetic branch of the ANS control?Fight or flight
- 4What does the parasympathetic branch of the ANS control?Rest and digest
- 5The brain hemispheres are connected by what?Corpus colossum
- 6How many cranial nerves are there?12
- 7Name a cranial nerve that is: just sensory, just motor, bothSensory - olfactory bulb
Motor - hypoglossal nerve (tongue)
Both - vagus nerve - 8How many pairs of spinal nerves are there?31
- 9What do dorsal roots do?Dorsal roots carry sensory information from spine to brain.
- 10What do ventral roots do?Carry motor information from brain to effector muscle.
- 11What direction is dorsal?Top of head
- 12Where does ventral point?Down to stomach
- 13Where does anterior point?To the front
- 14What is side to middle called?Lateral -> medial
- 15What are the bumps in the brain called? What are the folds in the brain called?Gyrus
Sulcus - 16Describe the movements of the coronal pathway?Anterior to posterior
- 17Describe the movements of the saggital pathway?lateral>medial>lateral
- 18Describe the movements of the axial pathway?Dorsal to ventral
- 19Two types of subcortical brain systems and their functionsBasal ganglia (motor skills)
Limbic system (olfactory, amygdla(emotion), hippocampus (memory)) - 20How is the brain protected within the skull?Cerebral fluid, meninges (3 layers of protective tissue around the brain and spinal cord)
- 21Two types of cell in the brainNeurons, Glial cells
- 22What part of the neuron is responsible for input? Output?Dendrites, Axon
- 23What are the four types of glial cell?Schwann cell (myelin sheath in PNS), Oligodendrocytes (Myelin in CNS) , Astrocyte (Regulates blood flow),
Migroglia (Multiply at injury & debris removal) - 24What lobe in the brain is responsible for spatial awareness?Parietal Lobe
- 25Which lobe in the brain is responsible for cognitive skills, language and emotionFrontal lobe
- 26Name a function of the cerebellumFine motor control
