HMB320H1 Lecture Notes - Inner Membrane, Pyruvic Acid, Ribosome
Document Summary
Readings: development of the nervous system (pages 187 to 192); differentiation of the. Midbrain; differentiation of the hindbrain; differentiation of the spinal cord; putting the. Pieces together; classification (pages 48 to 49); the prototypical neuron (pages 26 to 46) Differentiates into superior colliculus and inferior colliculus. Superior colliculus receives direct input from the eye: controls eye movement, cranial nerves iii and iv. Inferior colliculus receives direct input from the ear. Relay station en route to the thalamus. Contains both the substantia nigra (black substance) and the red nucleus: both are involved in control of voluntary movement. Other cell groups have axons that project widely throughout cns: regulate consciousness, mood, pleasure and pain. Conduit for information passing from the spinal cord to the forebrain and vice versa. Axons descending from cerebral cortex to brain stem and spinal cord (ex: corticospinal tract) Damage results in loss of movement to opposite side. Contribute to: sensory systems, control of movement, several other functions.
