Question 6

Name the two muscles of hip flexion, two muscles of hip abduction one muscle of hip extension and four muscles of hip adduction.

Answer 6

Flexion: Psoas, Illiacus
Extension: Gluteus Maximus
Abduction: Gluteus Medius, TFL
Adduction: Adductors

Question 7

Name the 4 muscles of knee extension and four muscles (bicep femoris long and short head) of knee flexion. Make sure you know which direction is knee extension and knee flexion.

Answer 7

Rectus femoris, Vastus lateralis, Vastus Medialis, Vastus intermedius

Question 8

Name the muscle of ankle dorsiflexion and two muscles of ankle plantar flexion.

Answer 8

Dorsiflexion: Tibialis Anterior
Flexion: Gastrocnemius and Fibularis Longus

Question 9

linea alba

Answer 9

band of tough connective tissue called the linea alba extends from the xipgoid process of the sternum to the pubic symphasis
increases pressure
presses air out

Question 10

pelvic floor

Answer 10

muscular base of abdomen, attatched to pelvis

Question 11

IT band

Answer 11

Iliotibial band is a layer of connective tissue extending from the iliac crest to the knee and links the gluteus maximus to the tibia.

Question 12

patellar tendon

Answer 12

A tendon that extends down from the quadriceps muscle in the thigh to incorporate the patella (the kneecap) and attach it to the tibia (the shinbone), providing extension at the knee joint. The patellar tendon is also called the patellar ligament because it connects the patella to the tibia.

Question 13

calcaneal tendon

Answer 13

The Achilles tendon (or occasionally Achilles’ tendon), also known as the calcaneal tendon or the tendo calcaneus, is a tendon of the posterior leg. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone.

Question 14

define CNS

Answer 14

Brain and brainstem

Question 15

PNS

Answer 15

all other nerves

Question 16

somatic nervous system

Answer 16

nerves that you can control

Question 17

neuron

Answer 17

mass of nerve cells

Question 18

axon

Answer 18

extensions that send information in the form of nerve impulses

Question 19

neuroglia

Answer 19

provide physical support, insulation, an nutrients for nuerons

Question 20

sensory receptor

Answer 20

sensory function of nuero receptors

Question 21

effector

Answer 21

the motor functions are carried from impulses called effectors

Question 22

oligodendrocyte

Answer 22

align along nerve fibers. Provide layers of myelin sheet around axons in CNS

Question 23

Shwann cell

Answer 23

In PNS produce myelin sheet around axons

Question 24

neurotransmitter

Answer 24

Synaptic transmission, bio chemicals

Question 25

Resting potential

Answer 25

difference between region inside membrane and the outside is the resting potential

Question 26

Action Potential

Answer 26

once threshold reaches 55 millivolts it is at action potential

Question 27

Repolarazation

Answer 27

In neuroscience, repolarization refers to the change in membrane potential that returns the membrane potential to a negative value after the depolarization phase of an action potential has just previously changed the membrane potential to a positive value. …

Question 28

Depolarazation

Answer 28

the reduction of a membrane potential to a less negative value. It is caused by the influx of cations, such as sodium and calcium, through ion channels in the membrane. In many neurons and muscle cells, depolarization may lead to an electric impulse called an action potential.
