Study Notes
Neurons
-
Structure:
- Dendrites: receive signals
- Cell body: contains nucleus, maintains cell functions
- Axon: transmits signals
- Terminal buttons: release neurotransmitters
-
Functions:
- Receive and transmit signals
- Integrate and process information
-
Types:
- Sensory neurons: transmit sensory info
- Motor neurons: transmit motor signals
- Interneurons: integrate and process info
Endocrine Glands
-
Major glands:
- Pituitary gland: regulates other endocrine glands
- Thyroid gland: regulates metabolism
- Adrenal glands: regulate stress response
- Pancreas: regulates blood sugar levels
- Ovaries and testes: regulate reproductive functions
-
Functions:
- Produce and secrete hormones
- Regulate various bodily functions
Hormone Regulation
-
Hormone types:
- Steroid hormones (e.g. estrogen, testosterone)
- Peptide hormones (e.g. insulin, growth hormone)
-
Hormone regulation mechanisms:
- Negative feedback loops
- Positive feedback loops
-
Hormone regulation importance:
- Maintains homeostasis
- Regulates growth and development
Nervous System Disorders
-
Neurological disorders:
- Alzheimer's disease: progressive cognitive decline
- Parkinson's disease: motor function impairment
- Multiple sclerosis: demyelination of nerve fibers
-
Neuropsychiatric disorders:
- Depression: mood regulation impairment
- Schizophrenia: thought and perception impairment
- Anxiety disorders: excessive fear and anxiety responses
-
Treatment approaches:
- Medications (e.g. antidepressants, antipsychotics)
- Therapies (e.g. cognitive-behavioral therapy, physical therapy)
- Lifestyle changes (e.g. exercise, stress management)
Test your knowledge of the nervous system, including the structure and function of neurons, endocrine glands, and hormone regulation. Also, learn about common nervous system disorders and their treatment approaches.
