Study Notes
Operational Definition of Dependent Variables
- The dependent variable in the study is appetite regulation.
- It is measured by participant's food intake in response to stimuli.
- Self-reported feelings of hunger and fullness are also part of the measurement.
- Physiological markers, like hormone levels, are quantified.
Nervous System
- The nervous system is the body's communication network.
- It consists of a complex system of nerves, neurons, and specialized cells.
Central Nervous System (CNS)
- The CNS comprises the brain and spinal cord.
- It functions as the body's command center.
- It processes information, coordinates responses, and regulates bodily functions.
- The spinal cord acts as a vital pathway for transmitting sensory information and motor commands between the body and brain.
Peripheral Nervous System (PNS)
- The PNS consists of all the nerves and ganglia located outside the brain and spinal cord.
- It acts as a communication network, transmitting sensory information from the body to the CNS.
Autonomic Nervous System
- This division of the PNS regulates involuntary bodily functions.
- It operates automatically, without conscious control.
- It has two main branches: the sympathetic and parasympathetic systems.
Sympathetic Nervous System
- It activates the body's "fight or flight" response during stress or danger.
- It increases heart rate, dilates airways, and redirects blood flow to essential organs.
Parasympathetic Nervous System
- It promotes relaxation and restores the body to a calm state after experiencing stress or danger.
- It slows heart rate, constricts airways, and enhances digestion.
Somatic Nervous System
- This PNS division controls voluntary movements and relays sensory information.
- It is responsible for coordinating voluntary movements, including those involved in skilled activities like playing a musical instrument, as well as for relaying sensory information.
Neurons
- Neurons are specialized cells that serve as the building blocks of the nervous system.
- They transmit electrical and chemical signals throughout the body.
- They consist of a cell body (soma), dendrites, and an axon.
Glial Cells
- Glial cells are support cells in the nervous system.
- They provide structural support, insulation, and nourishment to neurons.
- They play essential roles in maintaining brain health and supporting neuronal functions.
Motor Neurons
- Motor neurons transmit signals from the CNS to muscles, glands, and organs, enabling voluntary and involuntary movements.
Sensory Neurons
- Sensory neurons detect various stimuli (touch, temperature).
- They send signals to the CNS.
- These neurons convert stimuli into electrical signals that the brain processes.
Interneurons
- Interneurons function as connectors within the CNS.
- They relay signals between sensory and motor neurons, coordinating movement.
Reflex Arc
- The reflex arc controls reflex actions.
- Reflex actions are automatic responses to sensory stimuli, occurring without conscious thought.
- Sensory neurons detect stimuli, transmit signals to the spinal cord, where interneurons relay this information to motor neurons.
- Motor neurons trigger quick muscle responses.
Homunculus Mapper
- The homunculus mapper is a brain map of the body on the cortex.
- The mapping isn't proportional to the body parts' actual size.
- It can be used to test sensitivity using two-point discrimination.
