Chapter 26, Problem 1PIT
Summary Introduction
To add:
The term homeostasis in the concept map.
Concept introduction:
The brain is the important organ of the central nervous system. The average weight of the brain is about 1.4 to 1.6 kilograms. Brain is anatomically subdivided into three parts forebrain, midbrain, and hindbrain. The forebrain is the front portion of the brain. Midbrain is the region that connects the forebrain to hindbrain and hindbrain is the lower back region of the brain.

Which does NOT describe nervous tissue?
Group of answer choices
Cells may have long extensions
When activated, shortens
Involved in fast-acting body control
Found in the brain and spinal cord
Draw a figure illustrating the balance concept in homeostasis.
Research the behaviours of a specific ectothermic animal. How do specific behaviours allow for the animal to control its body temperature in cool and hot conditions? How do specific parts of the animal’s anatomy help with thermoregulation?
Use a feedback diagram to show how this animal uses thermoregulation in one of these conditions:
ectotherm in cool conditions
ectotherm in hot conditions
Be sure to use ⊕ and ⊝ symbols in the feedback diagram to add important details.
