Identify the effectors in this homeostatic reflex: Eating a salt-rich meal increases blood volume and pressure, stretching blood vessel walls. Nerve signals sent to the brainstem stimulate changes in hormonal and neural signaling. The heart rate is slowed, blood vessel walls are relaxed, and the kidneys increase urinary salt. The blood pressure returns toward normal.
Thermoreceptors
Thermoreceptors are sensory receptors that detect changes in temperature, enabling the sensation of warmth or cold.
Ciliary Muscle
A ring of smooth muscle in the eye's middle layer that changes the shape of the lens for focusing.
Suspensory Ligaments
Fibrous tissues that connect the lens of the eye to the ciliary body, adjusting the lens shape for focusing.
Fovea
A small depression in the retina of the eye where visual acuity is highest, due to the high density of cones, and no rods.
