Chapter 10 & 11 – Rhythms, Stress and Associated Hormones

10.1 Endocrine function shows rhythmic variation over time (Part 1)

10.1 Endocrine function shows rhythmic variation over time (Part 2)

10.1 Endocrine function shows rhythmic variation over time (Part 3)

10.2 Components of biological rhythms

10.3 De Mairan’s experiment

The plant shown is heliotropic, meaning it typically responds to sunlight for opening and closing. Yet, the researcher found this species would open in close cyclically in the absence of sunlight.

10.4 The diversity of biological rhythms (Part 2)

10.5 The collection of data on behavioral biological rhythms (Part 1)

10.5 The collection of data on behavioral biological rhythms (Part 2)

10.8 Ultradian rhythms in human plasma glucose level and insulin secretion rate

Ultradian rhythms are shorter rhythms and infradian rhythms are longer rhythms than circadian.

10.14 Circadian rhythms in human physiology and behavior

10.22 SCN damage disrupts the daily sleep–wake cycle in humans (Part 1)

10.22 SCN damage disrupts the daily sleep–wake cycle in humans (Part 2)

10.23 The three main components of a mammalian biological clock system

10.30 Melatonin measures night length

11.2 Catecholamine concentrations peaked on the day of a Ph.D. exam (Part 1)

11.2 Catecholamine concentrations peaked on the day of a Ph.D. exam (Part 2)

11.3 Hypothalamic–pituitary–adrenal (HPA) axis releases several hormones in response to stress

11.4 Blood hormone concentrations are altered by the stress of parachute jumps (Part 1)

11.4 Blood hormone concentrations are altered by the stress of parachute jumps (Part 2)

11.7 Prolactin inhibits reproductive function (Part 1)

11.7 Prolactin inhibits reproductive function (Part 2)

11.8 Wound healing is impaired in stressed caregivers

11.11 Stress responses are reduced in offspring that received maternal attention as pups

11.12 Epigenetic influences of maternal behavior on offspring

11.17 Dominant male rats have lower corticosterone and higher testosterone when stressed

11.18 Exercise elevates testosterone in men

11.26 Leg-swinging displacement activity reduces heart rate

Hyperparathyroidism produces considerable osseous erosion and the development of brown tumors (osteoclastomas) and also osteoporosis.
