CBIS CHAPTER 2 QUESTIONS AND ANSWERS | CERTIFIED BRAIN INJURY
SPECIALIST STUDY GUIDE 2026
Why are the bony protuberances of the inside of the skull important? - correct answer
✔✔Possible shearing can cause damage
What are the three meninges of the brain? - correct answer ✔✔Pia, Arachnoid, Dura
What are the three main parts of a neuron? - correct answer ✔✔Cell body, axon, dendrite
What is the function of the blood brain barrier? - correct answer ✔✔It protects the brain, keep
in what's needed, keep out what's not needed
What is the role of a synaptic gap or cleft? - correct answer ✔✔It houses neurotransmitters
from one axon to affect receptor sites of another neuron
How might BI interrupt the ability of neurons to communicate? - correct answer ✔✔Through
damage to fibers/tracts between lobes of the brain, damage to axons can impact
communication between neurons
What are the functions of the midbrain? - correct answer ✔✔Seeing, hearing, arousal
What are consequences of midbrain damage? - correct answer ✔✔Coma, low level
consciousness, vision and hearing deficits
What are the functions of pons? - correct answer ✔✔facial movement/sensation, hearing, eye
movement
, What are consequences of pons damage? - correct answer ✔✔motor control deficits, impaired
communication between the cortex and the cerebellum
What are the functions of the medulla? - correct answer ✔✔Involuntary functions including
swallowing, respiration, blood pressure, heart rate, vomiting, sweating
What are consequences of medulla damage? - correct answer ✔✔dysphagia, impaired midline
orientation, life threatening impairments in heart/lung function
List four functions of the Reticular Activating System. - correct answer ✔✔arousal, alertness,
concentration, basic biological rhythm
What are the functions of the thalamus? - correct answer ✔✔relay station for sensory
information
What are consequences of thalamic damage? - correct answer ✔✔attention/concentration
problems, memory storage/retrieval deficits, reduced mental stamina
What are the functions of the hypothalamus? - correct answer ✔✔Hunger, thirst, sex response,
endocrine level, temperature regulation, anger, fatigue, memory, calmness
What are consequences of hypothalamic damage? - correct answer ✔✔Stress reaction, weak
emotional response, disordered eating/drinking/sex/sleep, hormone imbalance, neuro-
chemical imbalance, endocrine imbalance
What two structures are in the limbic system? - correct answer ✔✔Hippocampus, amygdala
What are the functions of the hippocampus? - correct answer ✔✔memory
