Biopsychology

Central nervous system

Brain, spinal cord

Brain

Occipital, temporal, parietal, frontal lobe

Occipital lobe

Visual information

Temporal lobe

Auditory information

Parietal lobe

Spatial navigation

Frontal lobe

Logical, reasoning, planning

Spinal cord

Transfer between brain and body, simple reflexes

Peripheral nervous system

Replay information between CNS and body

Somatic nervous system

Communicate CNS and environment, sensory and motor neurons, skeletal muscles

Autonomic nervous system

Homeostasis, maintain internal processes, motor neurons, smooth muscle and glands

Sympathetic nervous system

Fight/flight, increase heart hate, blood pressure, breathing, to organs

Parasympathetic nervous system

Restore body to normal

Motor neuron

info from CNS to muscle/glands in PMS, lower spine to muscle, upper brain and spine

Neurons

Send signals using neurotransmitters in the brain to body

Relay neuron

in CNS, pass info from sensory to motor neuron, short distance no myelin sheath

Sensory neuron

info from receptor in SNS to CNS, psychounipolar, axon 2 extension, cell body in middle

Reflex arch

Stimuli - Receptor - Sensory Neuron - Relay Neuron - Motor Neuron - Gland/muscle

Endocrine system

a network of glands across the body that secrete hormones in the blood to target cells

Hypothalamus

connected to pituitary gland and controls release of its hormones

Pituitary gland

master gland, hormone released stimulates release of other hormones

Anterior lobe

release ACTH stimulates adrenal cortex and cortisol

Posterior lobe

release oxytocin causing uterus contraction

Pineal gland

release melatonin responsible for biological rhythms

Thyroid gland

release thyroxine responsible for regulating metabolism

Adrenal gland

adrenal medulla and adrenal cortex

Adrenal medulla

inside, release adrenaline and noradrenaline for fight/flight

Adrenal cortex

outside, release cortisol stimulating glucose release and supress immune system

Testes

release androgens, testosterone, for puberty and muscle growth

Ovaries

release oestrogen for regulating reproductive system (menstrual cycle and pregnancy)
