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.
