Personal Development: Human Brain and Mental Health

Vocabulary flashcards on the structures and functions of the human brain, hemisphere roles, mental health concepts, and psychological disorders.

Human Brain

A complex organ that weighs about 3 pounds and consists of three essential parts: the forebrain, midbrain, and hindbrain.

Forebrain

Located in the uppermost part of the brain, it is the largest and most complex part, accountable for emotions, memory, and higher-order pursuits like thinking and reasoning.

Thalamus

Located between the cerebral cortex and the midbrain just above the brainstem; controls voluntary bodily movements, relays motor and sensory signals, and regulates sleep, alertness, and wakefulness.

Hypothalamus

A brain region in charge of homeostasis that produces hormones governing body temperature, thirst, hunger, sleep, circadian rhythm, moods, and sex drives.

Cerebrum

The largest segment of the brain containing the cerebral cortex; divided into left and right hemispheres comprising four sections called lobes.

Frontal Lobe

Located in the front of the brain, it collects information signals from other sections, forms personality, and influences decision-making and problem-solving.

Parietal Lobe

Located in the middle of the brain, it processes sensory information including taste, temperature, pressure, pain, and the body's position in space for cognitive purposes.

Temporal Lobe

Located at the lower part of the brain, it performs functions related to speech, perception, and some types of memory.

Occipital Lobe

Located at the back of the brain, it is responsible for visual processing, color recognition, visual movement, and interpretation.

Prefrontal Cortex

Located in the forebrain, it is associated with an individual's character and temperament.

Limbic System

Located inside the periphery of the cerebrum covering about 1/5 of the brain's volume; controls body functions like temperature and heart rate, forms memories, and links emotions with external stimuli.

Hippocampus

A small, seahorse-shaped structure located deep within the temporal lobe that plays an important role in forming new memories, learning, and remembering places.

Amygdala

A small, almond-shaped structure located deep within the temporal lobe strongly involved in emotions, fear/threat detection, and emotional memories.

Midbrain

Located at the top most of the brainstem, it is the smallest region of the brain involved in hearing, eye movement, and voluntary movement.

Hindbrain

Located in the upper portion of the spinal cord, comprising the brainstem and the cerebellum.

Brainstem

A structure of the hindbrain that regulates breathing, heartbeat, and digestive functions.

Cerebellum

A structure of the hindbrain that regulates voluntary movements such as posture, balance, speech, coordination, and movement.

Right Hemisphere

The creative side of the brain that focuses on visual content, face differentiation, entirety of perspectives, and controls muscles on the left portion of the body.

Left Hemisphere

The logical or analytical side of the brain that processes information sequentially and governs language comprehension, speaking, reading, writing, and attention.

Mental Health

A condition of the mind in which wellness is felt by the individual, where personal capabilities are recognized, situations are adapted to, and competencies are utilized for self and others.

Good Mental Health

A condition in which a person has a sense of mental steadiness that enables them to appreciate people and enjoy life fully.

Anxiety

A persistent and unlikely concern about routine daily life that may cause body signals such as butterflies, tension, or a sinking feeling.

Obsessive-Compulsive Disorder (OCD)

An anxiety disorder involving obsessions and compulsions characterized by uncontrollable and persistent thoughts, moods, beliefs, impressions, or actuations prompting repetitive actions.

Phobias

Extreme or irrational fears of specific things that lead people to avoid the feared stimulus to prevent panic attacks.

Arachnophobia

The extreme or irrational fear of spiders.

Aerophobia

The extreme or irrational fear of fresh air, airborne substances, or flying.

Agoraphobia

The extreme or irrational fear of being in a crowd or places where escape might be difficult.

Acrophobia

As defined in the text, the fear of being trapped in a small enclosed place.

Brontophobia or Astraphobia

The extreme or irrational fear of lightning and thunder.

Dysphagia

Physical difficulty swallowing.

Anorexia

A general lack of desire to eat, also termed loss of appetite.

Bipolar Disorder (Manic Depression)

A serious brain condition featuring extreme changes in mood and behavior, fluctuating between happy mood or 'mania' and extreme unhappiness.

Schizophrenia

A disorder characterized by disorderly and faulty perceptions, where individuals may speak nonsensically or remain motionless and silent for hours.

Panic Attacks

Instances of severe, alarming symptoms typically lasting from 5 minutes to 20 minutes, including breathing difficulty, chest pain, shaking, and a hard pounding heart.
