- Making plans and judgments. (correct)
- Regulating body temperature and hunger.
- Processing auditory information.
Which of the following BEST describes the primary function of the corpus callosum?
Which of the following BEST describes the primary function of the corpus callosum?
- Connecting the two brain hemispheres and facilitating communication between them. (correct)
- Regulating emotions and forming memories.
- Controlling voluntary movements of the body.
- Relaying sensory information from the body to the brain.
What is the main difference between the way the nervous system and the endocrine system transmit information throughout the body?
What is the main difference between the way the nervous system and the endocrine system transmit information throughout the body?
- The nervous system transmits information rapidly via electrochemical impulses, while the endocrine system transmits information slowly via hormones in the bloodstream. (correct)
- The nervous system is responsible for long-term regulation, while the endocrine system is responsible for immediate responses.
- The nervous system controls only voluntary movements, while the endocrine system controls only involuntary functions.
- The nervous system uses chemical signals, while the endocrine system uses electrical signals.

Study Notes
Nervous System Overview
- The nervous system is the body's electrochemical communication network
- It encompasses all nerve cells in the central and peripheral nervous systems
- The nervous system allows for fast communication throughout the body
Peripheral Nervous System
- The peripheral nervous system connects the central nervous system to the rest of the body
- It includes sensory and motor neurons
Central Nervous System
- The central nervous system includes the brain and spinal cord
Endocrine System
- The endocrine system is a "slow" chemical communication system
- It consists of glands that release hormones into the bloodstream
- Hormones act as chemical messengers
Hormones
- Hormones are chemical messengers
- They are produced by endocrine glands
- They travel through the bloodstream and affect various tissues
Limbic System
- The limbic system is a neural system
- It is located below the cerebral hemispheres
- It is associated with emotions and drives
- It includes the amygdala, hypothalamus, and hippocampus
Lobes of the Cerebral Cortex
- Frontal Lobes: Located behind the forehead, involved in speech, movement, planning, and judgment
- Parietal Lobes: Located at the top and rear of the head, process sensory input for touch and body position
- Occipital Lobes: Located at the back of the head, process visual information
- Temporal Lobes: Located above the ears, process auditory information
Cortical Areas
- Motor Cortex: Located at the rear of the frontal lobes; controls voluntary movements
- Somatosensory Cortex: Located at the front of the parietal lobes; processes body touch and movement sensations
Association Areas
- Association areas are parts of the cerebral cortex
- They are involved in higher-level mental functions like learning, memory, thinking, and language
Corpus Callosum
- The corpus callosum is a large band of neural fibers
- It connects the two brain hemispheres
- It allows for communication between the hemispheres
Neurogenesis
- Neurogenesis is the formation of new neurons
Consciousness
- Consciousness is subjective awareness of self and environment
Selective Attention
- Selective attention is focusing awareness on a specific stimulus
Inattentional and Change Blindness
- Inattentional and change blindness are related phenomena
- They represent a failure to notice changes in the environment
- It's a type of inattentional blindness
