Cerebrum
Higher cognitive functions (thinking, memory, emotions, voluntary movement)
Brainstem
Basic life functions (breathing, heart rate, sleep cycles)
Cerebellum
Balance, coordination, and fine motor control
Pons
Relays messages between cerebrum and cerebellum; regulates breathing
Corpus Callosum
Connects the left and right cerebral hemispheres for communication
Diencephalon
ensory and motor relay, hormone regulation (includes thalamus and hypothalamus)
Midbrain
Vision, hearing, motor control, alertness
Hypothalamus
Homeostasis (temperature, hunger, thirst, sleep)
LOBES
Frontal Lobe
- Primary functional systems: motor, motor planning, association areas
- Responsible for: attention, speech, personality, and motor
LOBES
Temporal
- Primary function systems: primary auditory sensory, secondary auditory sensory, association areas
-
Responsible for: special senses (hearing), auditory
processing, memory, receptive language
- Primary auditory cortex // Secondary auditory cortex
- anterior left temporal lobe (verbal info memory) // anterior right temporal lobe (retrieval of non-verbal memory)
- Wernicke’s area (retrieving, processing, and comprehension/meaning of words)
- Inferolateral temporal lobe: object recognition and visual memory
- fusiform gyrus: facial recognition
LOBES
Occipital
- interpretation of visual information // processing visual information
-
AREAS:
- Primary visual cortex (perceptions of edges)
- Ventral cortex (perceptions of shape, color, reading, face recognition, nonverbal pattern recognition)
- Dorsal cortex (depth and motion perception, visual attention, visually guided reaching)
LOBES
Parietal
- Sensory detection, Perception
- touch, spatial awareness, sensory integration
- Key Functional Areas
- Primary somatosensory cortex (postcentral gyrus)
- superior region // inferior region
- Secondary Sensory
Insula
Closely related to limbic system
-
Functions: interoception processing somatic,
visceral,
and taste sensations // emotional regulation // self-awareness - Key Functional Areas
- Posterior (interpretation of intensity of an experience
- Mid (association area)
- Anterior (interception // awareness internal state // visceral comfort and pain)
Cerebral Hemispheric Differences
Right Hemisphere
- Spatial relations
- Attention and awareness
- Understanding and remembering things we do and see
- Integrating information together to make an entire picture
- Contralateral motor planning (precentral gyrus), sensory processing (postcentral gyrus), visual processing
- Affective part of communications
Cerebral Hemispheric Differences
Left Hemisphere
- Numbers
- Logical comparisons
- Fact retrieval
- Analysis of information
- Contralateral motor planning (precentral gyrus), sensory processing (postcentral gyrus), visual processing
- Understanding and use of language (listening, reading, speaking and writing)
Cross section of spinal cord
spinothalamic tract
- sensory: pain, temperature, touch, pressure
Cross section of spinal cord
Lateral corticospinal tract
- MOTOR function (towards limbs)
Cross section of spinal cord
Dorsal columns
-
DCML: sensory
- proprioception and light touch
frontal lobe
precentral gyrus
- primary motor cortex,
- responsible for initiating
- controlling voluntary movements
the thalamus is a relay center for ___.
both motor and sensory nerves
a client comes in with thyroid problems and hormone imbalances.
what structure is impacted?
pituitary gland
a client had a stroke and they now have impaired reflexes and can't breathe on their own.
what structure is impacted?
brainstem
Your client says they are constantly hungry & thirsty.
what structure is impacted?
hypothalamus
