WHICH HEMISPHERE
Creativity and Art: Often associated with creativity, spatial ability, and artistic
expression.
RIGHT
WHICH HEMISPHERE
○ Emotional Processing: Plays a role in interpreting emotions, tone, and context.
RIGHT
WHICH HEMISPHERE
○ Intuition and Holistic Thinking: Tends to approach tasks in a more intuitive and holistic
manner.
RIGHT
WHICH HEMISPHERE
Language and Logic: Dominant for language processing, including speech, reading, and writing
LEFT
WHICH HEMISPHERE
○ Spatial Awareness: Crucial for understanding spatial relationships and recognizing faces.
RIGHT
WHICH HEMISPHERE
○ Detail-Oriented: Often better at tasks requiring precision and attention to detail.
LEFT
WHICH HEMISPHERE
Sequential Processing: Excels at tasks that require linear thinking, like following steps or
sequences
LEFT
WHICH HEMISPHERE
○ Analytical Thinking: Engages in logical reasoning, math, and problem-solving.
LEFT
: The largest part, responsible for higher cognitive functions (thought, memory, sensation, voluntary movement).
Cerebrum
●: Located at the back, under the cerebrum, it coordinates movement and balance.
Cerebellum
Extends from the brainstem and transmits signals between the brain and the body.
● Spinal Cord:
Regulates basic bodily functions such as heart rate, breathing, and blood pressure.
Medulla Oblongata:
BRAINSTEM COMPONENTS (2)
MEDULLA OBLONGATA
PONS
: Above the medulla; connects the cerebrum to the cerebellum and assists in coordinating movement and balance.
Pons
Located at the front of the brain; involved in the sense of smell.
● Olfactory bulb:
An X-shaped structure where the optic nerves cross, allowing visual
information from both eyes to be processed in both hemispheres.
Optic Chiasmata:
●: Shallow grooves on the brain’s surface that help increase its surface area.
Sulci
: Raised ridges between sulci, also contributing to an increased surface area for more neural
connections.
Gyri
Deep groove that separates the two cerebral hemispheres.
● Medial Longitudinal Fissure:
LOBES OF THE CEREBRUM (4)
FRONTAL
PARIETAL
TEMPORAL
OCCIPITAL
WHICH LOBE:
Controls reasoning, planning, speech, movement, and emotions.
● Frontal Lobe:
WHICH LOBE
Processes sensory information such as touch, temperature, and pain.
● Parietal Lobe:
: The central, narrow area of the cerebellum, helping integrate motor control from both hemispheres.
Vermis
WHICH LOBE:
Involved in hearing and memory.
● Temporal Lobe:
WHICH LOBE
Processes visual information.
● Occipital Lobe:
Thick band of fibers connecting the left and right hemispheres, allowing communication between them
Corpus Callosum:
Chambers within the brain filled with cerebrospinal fluid (CSF), which cushions the brain and removes waste.
Ventricles (Third and Fourth):
Acts as a relay station for sensory information heading to the cerebral cortex.
● Thalamus:
The “master gland” that releases hormones to control other glands in the body.
● Pituitary Gland:
: Regulates homeostasis, including temperature, hunger, thirst, and hormone
production.
Hypothalamus
Produces melatonin, involved in regulating sleep-wake cycles.
● Pineal Body (Gland):
Together form part of the brainstem and are involved in regulating basic life
functions and relaying information between brain regions.
● Pons and Medulla:
Latin for “tree of life,” this refers to the white matter in the cerebellum that appears tree-like when sliced, aiding in coordinating movement.
Arbor Vitae:
Composed of myelinated nerve fibers, it transmits signals rapidly within the brain.
Inner White Matter:
Contains neuron cell bodies and is involved in processing information; found in the cerebral cortex and the cerebellar cortex.
● Outer Gray Matter:
