exercise leadership

Plasmalemma

contains acetylcholine receptors

acetylcholine

primary neurotransmitter for motor neurons

Gluconeogenesis

creating glucose from a non-carb source. lactic acid, glycerol, alanine amino acid

lactic acid

formed anaerobically when H+ joins pyruvate

phosphogens

ATP and PCR

beta oxidation

turns fatty acids inyo acetylCOa

cori cycle

glucose is made from lactate in liver, type of gluconeogenesis

Sodium

Na+, outer cell dominant ion

kreb cycle

nets 2 ATP and NADH and FADH

smooth muscle

muscle in the digestive tract

Type 1 fiber

slow twitch oxidative

axon

The neuron's transmitter, conducting impulses away from the cell body

Myoglobin

hemoglobin in muscle

axon hillock

graded potentials gather

action potential

rapid and substantial depolarization of the neurons membrane

Type 2 fiber

fast twitch, white stained

D.O.M.S

soreness and pain due to muscle protein damage

Elasticity

muscles return to resting length

dendrite

recieve impulses

ATP

energy currency

NADH/FADH

coenzymes entering ETC

Na K pump

maintains RMP

Actin

muscle protein thin, movable binding sites

myofibril

composed of sarcomeres

ATPase

enzyme that spits the last phosphate group off of ATP

T tubules

extension of plasmalemma that passes nerve impules

ANS

parasympathetic and sympathetic

Pyruvate

byproduct of glycolysis

Calcium

find receptors on troponin to initiate muscle contractions

...

...

saltatory conduction

leaping from node to node

ligament

connects bone to bone

E.T.C

part of fat oxidation where H+ crosses cell membrane

myelin

a fatty substance insulated the cell membrane. Made of schwann cells

efferent

responsible for sending info from the CNS to various tissues + structures

Hyperpolarization

additional potassium moves out of cell, mv become more negative

Depolarization

sodium ions rush in, milivolts towards zero or more positive

axon terminal

tiny bulbs of synaptic knobs, containing acetylcholine

Cytoplasm

contains glycogen. Sarcoplasm

Sarcomere

functional unit of myofibril

sympathetic

fight or flight, pupils dilate

resting membrane potential

-70 mv

Synapse

junctions that allow neurons to communicate w/ each other

repolarization

potassium moves out of cell

Tropomyosin

surrounds actins binding sites for myosin head

Parasympathetic

rest and digest. Hands and warm and dry

Mitochondria

Powerhouse of the cell. where fat is metabolized

E. P. O. C

remove lactate restore body temp store glycogen. HR & BP decrease

afferent

sensory part of the peripheral nervous system

Sarcolemma

contains plasmalemma and basement membrane

Cerebrum

five lobes making up two hemispheres

graded potential

localized changes in the membrane potential, less than a 15 mv change.

muscle fiber

muscle cell

cerebellum

behind the brain stem and responsible for coordinating movement

hitting the wall

running out of available energy

Excitability

muscles are stimulated by nerves

Acetyl CoA

substance entering kreb cycle

Lipolysis

breakdown of fat

triglyceride

one glycerol and 3 fatty acids

myosin

muscle protein thick golf club head

Nodes of Ranvier

gaps in the myelin sheath

Potassium

K+. inner dominant cell ion

creatine

substrate in muscle for phosphagen system

CNS

brain and spinal cord

Adipose tissue

storage form of fat

neuro-muscular junction

where an alpha-motor neuron communicates with its muscle fiber

Troponin

contains binding sites for ca+

somatic

motor
