Study Notes
Nervous System Overview
- The somatic nervous system (SNS) enables conscious perception and voluntary motor responses, primarily controlling skeletal muscle contractions.
- The autonomic nervous system (ANS) manages involuntary body functions crucial for maintaining homeostasis.
Brain Structures
- The cerebrum is the largest brain region, responsible for awareness-based functions such as problem-solving, speech, and voluntary muscle movements.
- The cerebellum, located beneath the cerebrum, manages body position, coordination, and balance, essential for tasks like biking and handwriting.
- The brain stem is the smallest region, controlling automatic body functions such as breathing, heart rate, and digestion.
- The spinal cord is a tube of neurons extending from the brain stem to the lower back, facilitating the flow of nerve impulses between the brain and body.
Endocrine System Components
- Hypothalamus: Regulates hormones controlling the pituitary gland and manages functions like sleep-wake cycles, body temperature, and appetite.
- Pituitary Gland: Situated below the hypothalamus, it secretes hormones that influence growth, reproduction, and other endocrine glands.
- Pineal Gland: Central in the brain, this gland is crucial for regulating sleep-wake cycles.
- Thyroid Gland: Located in the neck, it plays a key role in metabolism regulation.
- Parathyroid Glands: Also in the neck, these glands help control calcium levels in bones and blood.
- Thymus: Found in the upper torso, it is active until puberty and produces hormones critical for the development of T cells, a type of white blood cell.
- Adrenal Glands: Positioned atop each kidney, these glands are vital for producing hormones that regulate blood pressure, heart rate, and stress responses.
- Pancreas: Located behind the stomach, its endocrine function is primarily to control blood sugar levels.
