Document Summary
Analogy: forming a fist; diencephalon = fist level, midbrain is wrist, and brain stem is the forearm. Cerebral peduncle a fibre tracts connecting the cortex, cerebellum and spinal cord. Still intact blindside reflective changes herman von. Tegmentum covering or midbrain floor; and surrounds the cerebral aqueduct . Colourful region of the brain (red nucleus, substantial nigra damage to substantial nigra can lead to lack of dopamine loss of dopaminergic pathways e. g. parkinson"s) Dinecephalon --> midbrain --> hindbrain (consists of pons and medulla, cerebellum (density of neurons very high here) top down. Structures lower down are more fundamental; more primitive as you get down. Reticular formation in the brain stem; reticular activating system. Reticular; full of holes (e. g. swiss cheese) reticulated structures are full of holes; tracts pass through. Pass through internal capsule damage to region can result in many symptoms.
