Chloroplasts are one of several different types of plastids, plant cell organelles that are involved in energy storage and the synthesis of metabolic materials. The colorless leucoplasts, for instance, are involved in the synthesis of starch, oils, and proteins.
The hypothalamus regulates emotional responses through its influence on the pituitary gland, skeletal muscular system, and autonomic nervous system. Hypothalamus: Function. The hypothalamus is involved in several functions of the body including: Autonomic Function Control; Endocrine Function Control; Homeostasis; Motor Function Control
The hypothalamus plays a key role in regulating autonomic function, usually as part of more generalized, often quite stereotyped, behavioural responses triggered by internal challenges (e.g., a change in body temperature or blood glucose levels) or external threats (e.g., the sight, sound or odour of a predator).he hypothalamus plays a key role in regulating autonomic function, usually as part of more generalized, often quite stereotyped, behavioural responses triggered by internal challenges (e.g., a change in body temperature or blood glucose levels) or external threats (e.g., the sight, sound or odour of a predator).
