Week 5 Part 2 Flashcards
What protects the central nervous system
Bones, cerebrospinal fluid, meninges
Afferent
Going towards the spine
Sensory, involuntary
Efferent
Going away from the spine
Voluntary, motor
The hole of the skull
Foremen magnum
The ramps of the spinal nerves
Called spinal roots
Which connect the spinal nerves to the spinal cord
How many spinal nerves are there
31 pairs of spinal nerves
How many cervical nerves
8
How many lumbar nerves
5
How many thoracic nerves
12
How many sacral nerves
5
How many coccygeal nerves
1
How many lobes are there and what are there names
Frontal lobe
Occipital lobe
Parietal lobe
Temporal lobe
Frontal lobe
“Executive functions”, motor activities
Emotion and behaviour,
Thinking
Smell and speech
Occipital lobe
Vision
Parietal lobe
Body sense, perception, and language comprehension
Temporal lobe
Hearing, speech, language and integration of emotions
Speech centres of the brain
Frontal lobe and parietal lobe
Frontal lobe is in which area and responsible for what
Broca’s area
Speech output
Partietal lobe is in which area and responsible for what
Wernick’s lobe
Language, understanding
Cerebellum involved in what
Sensory and motor coordination and balance
The parts of the brain stem
Midbrain, pons, medulla oblongata
Midbrain is responsible for
relay visual and auditory impulses to the cerebrum
Pons is responsible for
Respiration
Medulla oblongata responsible for
Controls heartbeat, respiration, and blood vessel diameter
Diencephalon responsible for
Hormones, hunger and thirst, body temp., sleep-wake cycle, sending information
The four parts of diencephalon
Thalamus, hypothalamus, pineal body, pituitary gland
Hypothalamus
Controls or inhibits the release of hormones
Pituitary gland
Produces and release hormones
Pineal body
Produce and secrete the hormone melatonin
Thalamus
Body’s information relay station
Reflexes
The sensory impulses do not make it to the brain
Quadriplegia
Paralysis of all four limbs
Paraplegia
Paralysis of the lower extremity
Stroke
A disruption of blood flow to the brain
Changes with aging process for nervous system
Reaction time slows
Impulses don’t travel as fast
Longitudinal fissure
Divides the brain into the right and left hemisphere
Transverse fissure
Divides the cerebellum from the rest of the brain
The order of the parts of the brain stem
The midbrain
The pons
Medulla oblongata
Centralateral
Left side of your body is controlled by the right side of your brain
Right side of your body is controlled by the left side of your brain
Central sulcus
Lateral sulcus
Longitude sulcus
Precentral gryus
Postcentral gyrus
White matter
Myelinated
Grey matter
Unmyelinated
