Study Notes
Nervous System
Functions:
- Controls and coordinates body functions
- Interprets and responds to sensory information
- Facilitates communication between different parts of the body
- Regulates body functions, such as movement, sensation, and emotions
Components:
-
Central Nervous System (CNS): brain and spinal cord
- Interprets and integrates information
- Controls voluntary actions
-
Peripheral Nervous System (PNS): nerves outside the CNS
- Transmits information to and from the CNS
- Divided into sensory (receives information) and motor (transmits information) nerves
-
Neurons: specialized cells that transmit and process information
- Dendrites: receive signals
- Cell Body: contains nucleus and organelles
- Axon: transmits signals
- Terminal Buttons: release neurotransmitters
Endocrine System
Functions:
- Produces and regulates hormones that control various body functions
- Maintains homeostasis and regulates growth and development
- Interacts with the nervous system to control body functions
Components:
-
Endocrine Glands: produce and secrete hormones directly into bloodstream
- Pituitary Gland: master gland that regulates other endocrine glands
- Thyroid Gland: regulates metabolism
- Adrenal Glands: regulates stress response and electrolyte balance
- Pancreas: regulates blood sugar levels
- Ovaries and Testes: produce sex hormones
-
Hormones: chemical messengers that regulate body functions
- Steroid Hormones: derived from cholesterol
- Peptide Hormones: derived from amino acids
Interaction between Nervous and Endocrine Systems
- The nervous system regulates the release of hormones from endocrine glands
- Hormones can affect the nervous system by binding to receptors on neurons
- Both systems work together to maintain homeostasis and regulate body functions
Nervous System
Functions
- Coordinates and controls body functions, such as movement, sensation, and emotions
- Interprets and responds to sensory information from the environment
- Facilitates communication between different parts of the body
Components
Central Nervous System (CNS)
- Consists of the brain and spinal cord
- Interprets and integrates information
- Controls voluntary actions
Peripheral Nervous System (PNS)
- Comprises nerves outside the CNS
- Transmits information to and from the CNS
- Divided into sensory nerves (receive information) and motor nerves (transmit information)
Neurons
- Specialized cells that transmit and process information
- Have three main parts: dendrites, cell body, axon, and terminal buttons
- Dendrites receive signals
- Cell body contains nucleus and organelles
- Axon transmits signals
- Terminal buttons release neurotransmitters
Endocrine System
Functions
- Produces and regulates hormones that control various body functions
- Maintains homeostasis and regulates growth and development
- Interacts with the nervous system to control body functions
Components
Endocrine Glands
- Produce and secrete hormones directly into the bloodstream
- Include pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries, and testes
- Pituitary gland is the master gland that regulates other endocrine glands
Hormones
- Chemical messengers that regulate body functions
- Can be steroid hormones (derived from cholesterol) or peptide hormones (derived from amino acids)
Interaction between Nervous and Endocrine Systems
- Nervous system regulates the release of hormones from endocrine glands
- Hormones can affect the nervous system by binding to receptors on neurons
- Both systems work together to maintain homeostasis and regulate body functions
