Card 6

Front

This descending pathway is involved in voluntary movement and uses distal muscles and flexors

Card 7

Front

This descending pathway is involved in posture and it uses proxima/axial muscles and extensors

Card 8

Front

A lateral pathway which is also known as the pyramidal tract. There is monosynaptic contact with alpha motor neurones which controls the distal muscles and the flexors

Card 9

Front

A lateral pathway which takes over from the corticospinal pathway if it gets damaged. Otherwise it only has a minor role

Card 10

Front

A ventromedial pathway which relays gravitational sensory information from the inner ear and axial muscles. It maintains the head and neck positions and also the legs

Card 11

Front

A ventromedial pathway which relays visual sensory information in order to orientate the head and eyes in response to the stimuli

Card 12

Front

A ventromedial pathway which enhances anti-gravity reflexes of the spinal cord - keeps the body upright

Card 13

Front

A ventromedial pathway which frees anti-gravity muscles from reflex control to allow voluntary override in order to sit down for example (opposite of pontine reticulospinal)

Card 14

Front

The part of the brain that has control over axial muscle tone, posture/balance, eye movement and sensory -motor integration

Back

Card 15

Front

This part of the brain integrates sensory and motor information, selects and initiates voluntary movement but its output to the thalamus is inhibitory
