Brain development
what are the three primary vesicles
Forebrain, midbrain, hindbrain
What does Longitudinal fissure do
Separates two hemispheres
Nociceptors
Sensitive to pain-causing stimuli
How many pairs of cranial nerves are associated with the brain
12
Muscles tissues consist of
all contractile tissues
For the five secondary brain vesicles forebrain becomes
Telencephalon and diencephalon
What are the five lobes
Frontal, parietal, temporal, occipital, insula
Receptors have either or
Nonencapsulated (free) nerve endings or encapsulated nerve endings
Olfactory nerves
sensory nerves of smell located within special sense organs
What is ancons
Elbow
What primary vesicles remains undivided
Midbrain
Central sulcus seperates
Precentral gyrus of frontal lobe and postcentral gyrus of parietal lobe
Sensation vs perception
Sensation: awareness of changes (feel)
perception: conscious interpretation of those stimuli (understand)
What nerves have sensory functions of taste
Facial, glossopharyngeal, vagus nerves
What is the major extensor of thigh
Gluteus Maximus
What is the brain stem
Midbrain, pons, medulla oblongata
Pyramidal cells
are large neurons that allow conscious control of precise, skilled, skeletal muscle movements
Levels of neural integration
Receptor level, circuit level, perceptual level
What is the only cranial nerve that extends beyond head and neck
Vagus nerves
What two pronate the forearm
Pronator teres and pronator quadratus
Diencephalon becomes
Epithalamus, thalamus, hypothalamus, and retina
left hemisphere controls
Language, math, and logic
Visceral vs referred pain
Visceral: results from stimulation of visceral organ receptors (vague aching, burning)
referred pain: pain from one body region perceived as coming from different regions
What cranial nerve motor functions include facial expression, parasympathetic impulses to lacrimal and salivary glands
facial nerves
What straplike superficial muscle runs across anterior surface of the thigh to knee
Sartorius
