Study Notes
Human Nervous System
- A complex network of neurons that carry messages.
- Two parts: Central Nervous System (CNS) and Peripheral Nervous System (PNS).
Central Nervous System (CNS)
- The central processing unit of the body.
- Composed of the brain and spinal cord.
- Enclosed within the skull, lateral, and dorsal protection.
- Three major parts: Forebrain, Midbrain, and Hindbrain.
Forebrain
- Anterior part of the brain.
- Contains Cerebrum, Hypothalamus, and Thalamus.
- Cerebrum: Largest part, two hemispheres (Right- creativity; Left- speech/logic).
- Hypothalamus: Body's control center for homeostasis (hormones).
- Thalamus: Information relay station (all senses, except small).
Midbrain
- Small and central part of the brainstem.
- Connects cerebrum to spinal cord and cerebellum.
Hindbrain
- Composed of Cerebellum, Medulla, and Pons
- Cerebellum: Responsible for balance, muscle control, and language processing.
- Medulla Oblongata: Manages heart, circulation, and breathing.
- Pons: Provides a route for signals travelling in and out of the brain.
Peripheral Nervous System (PNS)
- Lateral part of the NS
- Connects different parts of the body with the CNS
- Two types of nerve fibres are :
- Efferent nerve fibres: Responsible for conveying messages from CNS to peripheral organs.
- Afferent nerve fibres: Responsible for transmitting sensory information from the body to the CNS.
- Somatic Nervous System: controls voluntary actions.
- Autonomic Nervous System: controls involuntary actions such as digestion.
Parts of the Neuron
- Dendrites: Short fibers extending from the cell body.
- Axon: Longest fiber extending from the cell body.
- Cell Body: Contains cytoplasm and the nucleus.
- Synapse: Microscopic gap between neurons.
The Heart
- A pump with two sides (right/left pumps).
- Pumps blood to both lungs (right) and body (left).
- Pumps about 5 liters of blood per minute.
- Has four chambers (Right atrium/ventricle, left atrium/ventricle).
Cardiovascular System
- Network of heart, blood vessels, and blood.
- Heart pumps blood throughout the cardiovascular system.
Respiratory System
- Structures acquire oxygen and remove carbon dioxide.
- Includes: nose, nasal cavity, pharynx, larynx, trachea, bronchi and bronchioles, alveoli.
- Functions: warming, filtering and moistening (air), oxygen/gas exchange
Digestive System
- Breaks down food into nutrients.
- Includes: mouth, pharynx, esophagus, stomach, small intestine and large intestine.
- Accessory organs: liver, gall bladder, and pancreas.
- Mechanical and chemical digestion.
Urinary System
- Main function is to filter blood.
- Includes: kidneys, ureters, urinary bladder, and urethra.
- Filters waste and maintains homeostasis
Endocrine System
- Network of glands and organs that produce hormones.
- Includes: pineal gland, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, pancreas, ovaries, testes.
- Hormones: chemical messengers that regulate various bodily functions.
Reproductive System (Male)
- Includes testes, scrotum, penis, urethra, seminal vesicles, prostate gland, and bulbourethral gland.
- Produces sperm and testosterone
Reproductive System (Female)
- Includes ovaries, fallopian tubes, uterus, cervix and vagina.
- Produces ova (eggs) and estrogen & progesterone.
