Study Notes
Nervous System Overview
- Comprises specialized cells (neurons and glia) for information communication regarding surroundings and internal states.
- Divided into two main categories: Central Nervous System (CNS) and Peripheral Nervous System (PNS).
- CNS includes the brain and spinal cord.
- PNS consists of cranial and spinal nerves, connecting sensory neurons to the CNS.
Peripheral Nervous System Functions
- Sensory (Afferent) Division:
- Involves somatic and visceral sensory nerves.
- Motor (Efferent) Division:
- Contains motor nerve fibers for response actions.
- Further divided into:
- Sympathetic Division: Activates "fight or flight" responses.
- Parasympathetic Division: Manages "rest and digest" activities.
Central Nervous System Regulation
- Important for central regulation functions, including:
- Feed intake regulation:
- Ventromedial area: Satiety center, prevents overeating.
- Lateral area: Feeding center, motivates appetite.
- Preoptic area: Regulates body temperature.
- Feed intake regulation:
Endocrine System Overview
- Composed of specialized organs and tissues producing, storing, and secreting hormones.
- Endocrinology: Branch of physiology focusing on body tissue coordination via chemical mediators.
Hormone Functions and Classifications
- Hormones play crucial roles in:
- Body growth and development.
- Control of various tissue functions.
- Support of pregnancy and reproductive activities.
- Metabolism regulation (catabolism and anabolism).
- Hormone classifications include:
- Simple proteins
- Glycoproteins
- Steroids
Major Endocrine Glands
- Key glands include:
- Hypothalamus
- Pituitary gland
- Thyroid and parathyroid glands
- Adrenal glands
- Pineal body
- Reproductive glands (ovaries and testes)
- The pancreas is also part of the endocrine system despite its primary digestive functions.
