Biology 30: Unit 1 Glands Hormones Neurons CNS/PNSEye/ Ear

Glands for 100 Known as the master gland, this gland is divided into the anterior and posterior lobes. Answer: Pituitary Gland Back

Glands for 200 This gland acts as both an endocrine gland and an exocrine gland. Answer: Pancreas Back

Glands for 300 When deprived of iodine, this gland can become a goitre. Answer: Thyroid Back

Glands for 400 The adrenal gland is divided into the outer portion, the cortex, and the inner portion, known as this. Answer: Medulla Back

Glands for 500 This structure produces releasing factors that influence the pituitary gland. Answer: Hypothalamus Back

Hormones for 100 This hormone, released from the pituitary gland, stimulates the thyroid gland. Answer: Thyroid Stimulating Hormone (TSH) Back

Hormones for 200 Known by the acronym ACTH, this hormone’s target is the adrenal cortex. Answer: Adrenocroticotrophic Hormone Back

Hormones for 300 When the pituitary gland secretes this hormone, the ovaries respond by developing a follicle. Answer: Follicle Stimulating Hormone (FSH) Back

Hormones This hormone causes the collecting ducts of the nephrons to become more permeable to water. Answer: Antidiuretic Hormone (ADH) Back

Hormones for 500 These are two name given to the hormone released by the adrenal gland that result in fight or flight responses. Answer: Epinephrine and Adrenalin Back

Neurons for 100 The condition of a neuron when sodium ions are being actively transported out of the neuron. Answer: Resting Potential Back

Neurons for 200 Action potential occurs when these gates open on the post synaptic membrane. Answer: Sodium Gates Back

Neurons for 300 This is the state of the post synaptic neuron when inhibitory neurotransmitters are released from the presynaptic neuron. Answer: Hyperpolarization Back

Neurons for 400 The minimum level of stimulus required for a neuron to depolarize. Answer: Threshold Back

Neurons for 500 An enzyme secreted by the presynaptic neuron immediately after acetylcholine is released that allows the post synaptic neuron to repolarize. Answer: Cholinesterase Back

CNS/PNS for 100 The part of the brain that coordinates complex actions such as walking and speaking. Answer: Cerebellum Back

CNS/PNS for 200 This root of the spinal column houses the cell bodies of the peripheral sensory neurons. Answer: Dorsal Root Back

CNS/PNS for 300 The unmeylinated neurons of the central nervous system make this stuff that matters. Answer: Grey Matter Back

CNS/PNS for 400 This branch of the central nervous system aids in the fight or flight response. Answer: Sympathetic Nervous System Back

CNS/PNS for 500 The lobes of the cerebrum that interpret visual and auditory stimuli, respectively. Answer: Occipital and Temporal Lobes Back

Eye/Ear for 100 The sclera, the retina and this make up the three tissue layers of the eye. Answer: Choroid Back

Eye/Ear for 200 The hammer, anvil and stirrup are collectively known as these. Answer: Ossicles Back

Eye/Ear Normal vision is sensed by the rods, which sense dim light, and the cones, which sense these three colours. Answer: Red, Green and Blue Back

Eye/Ear for 400 The ossicles amplify vibrations of the tympanic membrane and cause this structure to vibrate. Answer: Oval Window Back

Eye/Ear for 500 These funny areas of the eye contain fluid which refracts light to help focus images on the retina. Answer: Aqueous and Vitreous Humours Back
