Biology and Behaviour Flashcards
3 types of neurons in the nervous system?
Motor (efferent), interneurons, sensory (afferent)
Branches of the Autonomic Nervous System?
Sympathetic and Parasympathetic
Functions of the Parasympathetic Nervous System?
Constricts pupils, stimulates flow of saliva, constricts bronchi, slows HR, stimulates peristalsis and secretion, stimulates bile release, contracts bladder
Functions of the Sympathetic Nervous System?
Dilates pupils, inhibits salivation, relaxes bronchi, accelerates hearbeat, piloerection or sweating, inhibits peristalsis and secretion, stimulates glucose production and release, secretion of adrenaline and noradrenaline, inhibits bladder contraction, stimulates orgasm
Parts of the Hindbrain
cerebellum, medulla, oblongata, reticular formation
Parts of the Midbrain
inferior and superior colliculi
Parts of Forebrain
thalamus, hypothalamus, basal ganglia, limbic system, cerebral cortex
Thalamus
relay station for sensory information
Hypothalamus
maintains homeostasis and integrates with the endocrine system through the hypophyseal portal system that connects it to the anterior pituitary
Basal Ganglia
smoothens movements and helps maintain postural stability
Limbic System
controls emotion and memory includes septal nuclei (pleasure-seeking), amygdala (fear and aggression), hippocampus (memory), and fornix (communication within limbic system)
Four lobes of the cerebral cortex
Frontal, parietal, occipital, temporal
Frontal Lobe
Executive function, impulse control, long term planning (prefrontal cortex), motor function (primary motor cortex), speech production (Broca’s Area)
Parietal Lobe
Sensation of touch, pressure, temperature, and pain (somatosensory cortex); spatial processing, orientation, and manipulation
Occipital Lobe
visual processing
