Wernicke’s Area (Sensory Speech Area, Brodmann Areas 22, 39, 40) located at
TEMPORAL LOBE and the ANTERIOR PART OF THE PARIETAL LOBE
Receives visual input from the eyes, allowing you to perceive light,
shapes, and movement.
OCCIPITAL LOBE / PRIMARY VISUAL AREA (BRODMANN AREA 17)
PRIMARY AUDITORY AREA (BRODMANN AREA 41, 42) LOCATED AT
POSTERIOR PART OF THE TEMPORAL GYRUS
Connects sounds to memories, helping you identify familiar noises,
like a friend’s voice or music.
TEMPORAL LOBE/ SECONDARY AUDITORY AREA (BRODMANN AREA 22)
Secondary Auditory Area (Brodmann Area 22) located at
THE REST OF THE SUPERIOR PART OF THE TEMPORAL GYRUS
IT IS DIVIDED INTO 52 CYTOARCHITECTURAL AREA KNOWN AS
BRODMANN AREA
Where do Frontal lobe located
FRONT OF THE BRAIN
Where does your parietal lobe located?
NEAR TOP AND THE BACK OF YOUR HEAD
OCCIPITAL LOBE IS LOCATED AT
THE VERY BACK OF THE BRAIN
TEMPORAL LOBE IS LOCATED AT
SIDE OF THE BRAIN NEAR YOUR EARS
refer to the folds and grooves that
make up the surface of the cerebral cortex.
GYRUS (plural: GYRI) & SULCUS (plural SULCI)
These are the ridges or raised portions on the surface of the brain.
They help increase the surface area of the brain, allowing more neurons to be packed into the cortex for better processing power.
GYRUS ( plural: GYRI)
These are the shallow grooves or depressions between the gyri.
Like the gyri, sulci help increase the surface area of the cerebral cortex.
SULCUS (plural: SULCI)
these are two important areas located in the frontal lobe of the brain.
SUPERIOR FRONTAL GYRUS & MIDDLE FRONTAL GYRUS
is involved in self-awareness, higher
cognitive functions, and working memory. It’s thought to play a role in attention,
decision-making, and regulating behavior, including social behavior and
emotions.
SUPERIOR FRONTAL GYRUS
Superior Frontal Gyrus is located at
TOPMOST RIDGE OF FRONTAL LOBE (UPPER SIDE OF THE BRAIN)
It is associated with complex cognitive tasks,
such as reasoning, planning, and problem-solving.
MIDDLE FRONTAL GYRUS
MIDDLE FRONTAL GYRUS IS LOCATED AT
BELOW THE SUPERIOR FRONTAL GYRUS
is a major pathway that carries movement-related signals from the brain
to the spinal cord, enabling voluntary control of muscles.
CORTICOSPINAL TRACT
Refers to the cerebral cortex (the outer layer of the brain where motor control begins).
CORTICO
Refers to the spinal cord (which relays signals from the brain to the rest of the body).
SPINAL
The nerve fibers travel from the cortex, down through the brainstem, and into the
spinal cord. ((this is why the right side of the brain controls the left side of the body, and vice versa).
medullary pyramids
help maintain posture, stabilize the body, and support movements of
the head, neck, and trunk. They are involved in actions like bending forward, turning the head,
and stabilizing the spine.
AXIAL MUSCLES
AXIAL MUSCLES IS LOCATED AT
ALONG THE CENTRAL PART OF THE BODY
muscles are primarily responsible for movements of the larger joints, such as
lifting your arms, moving your legs, and stabilizing your shoulders and hips. They play a key role
in gross motor movements like walking, throwing, or lifting.
PROXIMAL MUSCLES
PROXIMAL MUSCLES ARE LOCATED AT
CLOSER TO THE BODY’S CORE
These movements are essential for scanning the environment,
reading, or switching focus between different objects.
SACCADIC EYE MOVEMENT
These impulses allow you to be aware of your body’s position in space
without having to look at it, helping you maintain balance, coordination, and posture.
Proprioceptive impulses
Specialized sensory receptors called proprioceptors are responsible for
detecting stretch, tension, and movement in muscles and joints. They send information to the
brain via the spinal cord.
PROPRIOCEPTORS
is the ability to perceive and recognize the form of an object using only the sense
of touch, without relying on visual input.
STEREOGNOSIS
It helps you perform tasks like reaching into your pocket and distinguishing between
objects
TACTILE PERCEPTION
This ability depends on the proper functioning of sensory pathways in the
brain, specifically in areas responsible for processing touch (somatosensory cortex).
Sensory Integration:
is part of the calcarine sulcus, a major groove located in the occipital
lobe of the brain, which is responsible for processing visual information.
POSTCALCARINE SULCUS
is a part of the brain located
in the occipital lobe. It is the first area in the cortex that processes visual information sent from the eyes.
STRIATE AREA
is a key structure located in the temporal lobe of the brain and
plays an important role in auditory processing and language comprehension.
SUPERIOR TEMPORAL GYRUS
plays a crucial role in
the processing of auditory information.
MEDIAL GENICULATE BODY
The medial geniculate body is located in the
THALAMUS
