Q

What is the response of our body to decreasing blood pressure?

final exam

A

When blood pressure drops too low, the rate of baroreceptor firing decreases. This triggers an increase in sympathetic stimulation of the heart, causing cardiac output to increase. Higher heart rate. It also triggers sympathetic stimulation of the peripheral vessels, resulting in vasoconstriction. Production of angiotensin II, Angiotensin II, antidiuretic hormone (ADH), epinephrine.†

138
Q

Whst are the layers of the heart, superficial to deep?

Epicardium
Myocardium
Endocardium

139
Q

What are the functions of the Tricuspid valve and the Bicuspid valve?

A

Tricuspid: Right side of the heart between atrium and ventricle,
keeps blood from flowing back to the atrium

Bicuspid (also called mitral) is between the left atrium and left ventrical. When oxygen rich blood flows into the left ventricle the mitral valve opens and allows it to flow into the left ventricle, and closes to make sure it doesn’t flow blackwards

140
Q

Whaere is the Pulmonary semilunar valve and where is it?

A

The pulmonary valve is located between the right ventricle and the pulmonary trunk.

141
Q

Where is the Aortic semilunar valve ?

A

Beween the left ventricle and the aorta

142
Q

The largest autonomic plexus is called the

A

celiac plexus

143
Q

Which of the following is NOT a function of a hormone?

a) Regulates chemical composition and volume of the internal environment
b) Regulates metabolism
c) Regulates glandular secretions
d) Produces electrolytes
e) Controls growth and development

A

D) hormones do not produce electrolytes

144
Q

The autonomic nervous system is involved in controlling what effectors? Select all that apply.

a) Exocrine glands
b) Skeletal muscle
c) Cardiac muscle
d) Smooth muscle
e) Endocrine glands

A

A, C, D and E

(not skeletal muscles)

145
Q

Autonomic motor neurons regulate visceral activities by (select all that apply):

  1. increasing activities in effector tissue.
  2. decreasing activities in effector tissue.
  3. allowing bidirectional conduction across synapses.
A

1 and 2

146
Q

What are the two types of glands?

A

Endocrine and exocrine

(Exocrine glands secrete non-hormonal substances into a ductal system to an epithelial surface, and endocrine glands secrete products directly into the bloodstream.)

147
Q

Differences between endocrine and exocrine glands include

A
  • endocrine glands secrete hormones while exocrine glands secrete non-hormonal substances
  • exocrine glands secrete their contents into ducts; endocrine glands have no ducts
148
Q

With respect to neurons, the term nerve fiber refers to what structure?

a) An axon
b) A dendrite
c) A Nissl body
d) Microtubules
e) Neurofibrils

A

An axon and a dendrite

149
Q

Which spinal meninges is composed of collagen fibers arranged in an irregular pattern that is very strong?

A

Arachnoid mater

150
Q

What is the outermost and the strongest of the meninges?

A

Dura Mater

(The middle layer is the arachnoid mater, and the inner-most layer lays directly on the nervous tissue of the brain or spinal cord, and is called the pia mater.)

151
Q

Spinal nerves

  1. are part of the PNS.
  2. connect the CNS to sensory receptors and effectors in all parts of the body.
  3. are named according to the region of the vertebral column from which they emerge.
  4. are mixed nerves.
  5. only transmit sensory information.
  6. only transmit motor information.

a) 1, 2, 3 b) 1, 2, 3, 4 c) 1, 3, 6 d) 1 and 3 e) 1, 2, 3, 6

midterm

A
