brain and neural Development

Question 1

nerons

Answer 1

a nerve cell that carries information between the brain and other parts of the body

Question 2

stimulus

Answer 2

A change in the environment that is straight by a receptor and receives a response

Question 3

response

Answer 3

A reaction/ change in an organism as a result of a stimulus

Question 4

Reflex

Answer 4

fast/ sudden, unconscious responese

Question 5

From what part are receptors in and what do they do?

Answer 5

are part of the nervous system that identify a stimulus and nerve impulses

Question 6

what are the many types of receptors?

Answer 6

temperature, pain, pressure receptors etc

Question 7

From what part dose a sensory neuron connects to and How it effects with rest of the connection?

Answer 7

Sensory neurons connect a stimulus into electro - chemical signal, which is carried through CNS and through the length of motor neuron which alters to cause a muscle/ gland to secrete (to produce a and reales liquid) a substance.

Question 8

what are relay nerons and what dose it do or help the process in response?

Answer 8

Relay neurons connect to neurons carry information down to the spinal cord - ascending and desascending neurons carry information to the brain (e.g a person touches something hot, that person only with drawn their hands but the information is sent to the brain, so it an remember and not it again)

Question 9

cerebral hemispheres

Answer 9

coordinating centre for learning memory, language and reasoning - recevice information form sense organs and coordinate and organise water functions

Question 10

hyopthalamus

Answer 10

controls autominmic nervous system - coordinates endocrine and nervous system by controlling and being in charge the secretions f the pituitary gland

Question 11

cerebullum

Answer 11

coordinates movement, posture, balance

Question 12

medulla oblongata (brain stem)

Answer 12

controls automatic and homostatic e.g breathing, swallowing, digestion, heart rate

Question 13

pituitary gland

Answer 13

releases the hormones oxytocin and APH from hypothalamus while anterior love produces and secretes seven hormones e.g FSH and growth hormone controls and being in charge in many of the body’s functions

Question 14

sympathetic nervous system

Answer 14

cause responses (for emergency) to fight or flight reponses

Question 15

parasympathetic nervous system

Answer 15

the system that controls functions that cannot be controlled, such as slowing the heart beat and producing tears

Question 16

neurulation

Answer 16

the nervous system develops from the outer layer (ectoderm) at a very early stage. An area on the dorsal surface develops into the neural plate.The plate folds inward to form a groove along the back
of the ball embryo. The groove closes to form a tube which becomes the central nervous system. The channel in the tube persists into adulthood and is visible in the spinal chord. As it closes the tube elongates.
