18
Q
  • Influenced by higher brain centers
  • Master command center for neural and endocrine coordination, regulates pituitary gland
  • Key to homeostasis regulation
A

Forebrain: Hypothalamus

19
Q

The brainstem includes structures such as:

A

pons, midbrain, medulla oblongata

20
Q

Produce 2 hormones: ADH & oxytocin
- Transported for release by posterior pituitary
- Produce releasing and inhibiting hormones transported & released by anterior pituitary

A

forebrain: hypothalamus

21
Q

motor control, maintains connections from cerebrum to cerebellum

A

midbrain functions

22
Q
  • Dopaminergic neurons project to basal nuclei and limbic system
  • Neurons leading to areas of the limbic system, hippocampus, amygdala and areas linking to the reward system are key areas for drug addiction studies
  • Dopamine (neurotransmitter & hormone- good feeling) is released in the nucleus accumbens (collection of neurons) after consumption of certain addictive drugs
A

midbrain

23
Q

cerebellum & pons

A

hindbrain

24
Q

sensory and motor tracts from the spinal cord, respiratory control centers

A

pons

25
Q

controls complex motor skills and coordinates movements and motor learning

A

cerebellum

26
Q

cerebellum receives info from areas of the body involved in movement:

A

muscles & joints (proprioceptors), skin, eyes

27
Q

Medulla Oblongata-
Autonomic nervous center functions:

A

cardio & respiratory

28
Q
  • All ascending & descending tracts between the brain & spinal cord pass through the medulla
  • Relay sensory info to the thalamus
A

medulla oblongata

29
Q

CNS: spinal cord

A

white matter surround gray

30
Q
  • interneurons, cell bodies of efferent neurons, axons of afferent neurons
  • shape gives rise to dorsal or posterior horn (connection for afferent fibers) and ventral or anterior horn (connection for efferent neurons)
A

gray matter

31
Q
  • myelinated axons or ascending/descending tracts
  • ascending carries sensory, descending carries motor impulses
A

white matter

32
Q

carries impulses from touch and pressure to the thalamus

A

spinothalamic (an ascending tract of white matter)

33
Q

cerebral cortex to spinal cord

A

coricospinal (spinal is descending tract of white matter)

34
Q

PNS Nerves:

A

spinal nerves

35
Q

spinal nerves all separate near the spinal cord into a dorsal root carrying ____ fibers and a ventral root carrying ____ fibers

A

sensory; motor

36

41
Q
  • A stimulus occurs at the receptor of a sensory neuron. This is sent along the afferent neuron as a nervous impulse and is received by the CNS
  • The interneuron makes connections to the motor neurons. The motor neuron transmits the impulse to the effector organ
A

reflex arc

42
Q

reflex responses to stimuli is a

A

multi-step process

43
Q

link afferent & efferent neurons directly together
- ex: knee-jerk reflex

A

muscle stretch reflex
