Epithalamus Ventral thalamus (subthalamus in BG) Dorsal thalamus Hypothalamus |
|
|
Epithalamus |
Pineal gland - pine cone. single midline structure, rostral to superior colliculi Endocrine gland related to seasonal light cycles - secretes melatonin (sleep wake, seasonal light cycles) Habenula nuclei Stria medularis |
|
|
Hypothalamus |
Links nervous and endocrine systems via hypophysis Neuroendocrine function: hypothalamic-releasing hormones, stimulate/inhibit secretion of pituitary hormones (growth etc) |
|
|
Hypothalamus regulatory function |
Regulates: bp, electrolytes, body temp, metabolism, functional systems (hunger, thirst, fatigue, circadian rhythm, reproduction, maternal, behaviours, emergency responses to stress)
Regulates by: sensory information from all area of body - blood sugar, hormone levels, temp, sodium Adjust system for homeostasis |
|
|
Internal medullary lamina |
Y shaped band divides thalamus into Anterior Medial Lateral Ventral |
|
|
Thalamus functional roles |
Sensory: all except olfactory relayed to cortex via thalamus Motor: from BG and cerebellum relayed by thalamus to cortex Emotion/memory: helps control some going to limbic cortex Vegetative: intrinsic nuclei associated with alertness and arousal |
